Thank you for this important information. Turn off the power, be careful not to bend any of the fins or copper tubing, and never open the refrigerant valves or tubing to the atmosphere. You may hear the unit humming and see that the contactor button is pulled in but nothing is happening. Of course, the first thing you'll notice is that your A/C isn't working and that the fan is not spinning. Thank you again and thank you to HP for selecting this for HOTD. Evaporator coil is defined, at AIR HANDLER / BLOWER UNITS TEVs, AEVs, thermostatic expansion valves, manual and adjustable expansion valves, and float valves are discussed, at THERMOSTATIC EXPANSION VALVES. Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. The fact is, and I know from experience, people can hardly afford energy costs therefore breakdowns force them to go without. winter. What I aim to do is explain only the parts of the condensing unit. Air conditioner compressor / condenser unit component parts guide: Here we describe each of the parts or components that make up the outdoor portion of an air conditioning or heat pump system: the compressor/condenser unit. It could be that because it ran that way it over heated and shut down by tripping a limit which might reset itself once it sits. Any idea on how to check if the fan/motor is 'bad' or the compressor is 'bad'? Answer: You'll need to find a contractor supply house near you. Dont be tempted to spray the unit with a hose to cool it. Atwood Hydro Flame 31501 RV Heater Ignition Control Board (Aug 2, 2014) Lou said:I have a carrier condensing unit that the compressor wont start.I have voltage at the contactor and have replaced the start cap and run cap.odd to say,im drawing 11 amps on start and run wires coming from the contactor but i hear nothing from the compressor! This mistake will surely cause problems if made. The coils either contain refrigerant or they don't. I was told my power board is bad in my unit. The fan was not spinning and the A/c is not running. Knowledge is power. Stay safe! Let's face it, having n You rock, Cre8tor! It's certainly not the type of bridge you care to play around with if you prefer to keep control of your own functions. Many times they malfunction, it is because of carbon build up on the surface that is to make contact. I have replaced the board and thermostat and not sure what to do next. on August 02, 2012: If electricity costs Increase we may have to resort to less exspensive methods of keeping our cool.Maybe heat transfer to and from pools of water. We need a new one, but Mel Flagg COA OSC from Rural Central Florida on August 01, 2012: Hey Cre8tor, congrats on another HOTD!!! We include more general compressor/condenser questions just below. Wifey needs it fixed, don't have her wait. COMPRESSOR / CONDENSER UNIT COMPONENT PARTS at InspectApedia.com - online encyclopedia of building & environmental inspection, testing, diagnosis, repair, & problem prevention advice. Here is where you may sometimes see that your A/C fuses are blown. So I'm suspecting a control or switch problem./, the outside unit of the heat pump is icing up on the compressor - Steve 8/7/11, Hi my fan in my house goes on but my compressor unit does not all the electric seems to be fine . Dan has been in the HVAC industry for 23 years with experience ranging from installation and service to sales and distribution. This restriction in refrigerant flow at the TEV is what allows the compressor a pressure difference between the high side and low sides of the system. Question: where can I get a condenser fan motor to replace an old one? When the air conditioner is asked to operate, the capacitor discharges this stored energy, providing a boost to get the motor going. All of your HVAC hubs are incredibly useful for us often-baffled homeowners. Some more modern, advanced air conditioning condensers do have an electronic control board but typically, what I've shown you is all you have in your condensing unit. could it be my thermostat? It replaces original OEM part numbers Dayton 1TDN7 Fasco 50747-D401 Century 9470 Fireplace Stove Blower We have no relationship with advertisers, products, or services discussed at this website. I notice the slap which holding the unit is slopping. Any suggestions? So summing up this theory and practice of air conditioning, the job of the air conditioning compressor is to reduce pressure on the low side (cooling side) of the system and to increase pressure on the high side (warming side) of the system. Marcy Goodfleisch from Planet Earth on June 03, 2012: Ah, yes - yet another piece of my home that's getting ready to crater! Assuming the unit worked before this. Wow, fantastic hub Cre8tor, now I can bookmark it instead of pestering you with questions lol. Voted up and rated awesome - keep up the fantastic work. This means that instead of a piston pushing up and down on the refrigerant, it is a rotating component that is doing the work. Marcy Goodfleisch from Planet Earth on August 01, 2012: I just had to check this one out again! So if there is an operating problem related to the system controls, the number of degrees below the room temperature to which the thermostat is set should make no difference in how long it takes the A/C system to start. NOTE: There is 220V passing across this drawbridge. That is parts that aren't proprietary or require an EPA license. This is a brand new direct replacement RV refrigerator thermocouple that fits Atwood Dometic. There is no opening them up and putting them back together. There are other things that are necessary to connect and help the system function, but they aren't dedicated solely to the A/C system. Thanks for keeping the answer to yourself. Atwood Dometic 30268 20494 RV Furnace Gas Burner You have taken a topic that is intimidating to most homeowners and given simple, well illustrated information that explains the basic parts of the air conditioning system. Question: My dog chewed the thermostat wire the contractor. Answer: Perhaps someone is referring to the contactor. The condenser it the proper name of this unit because it condenses the refrigerant back into a liquid from a gas. I am glad that I can be of help. The fan/motor and compressor are part of the unit. The contactor is what acts as the on/off switch so to speak. Here the condenser lid is removed so that you can see the fan and motor. Jaye Denman from Deep South, USA on August 01, 2012: This is an excellent hub, Cre8tor.It's so nice of you to share this specialized information, and you did it so well--photos and all. Air conditioning is all about the relationship between temperature and pressure. and also, does the condenser unit have to be leveled. It's not likely something anyone will stock so you'll likely be looking at the cost plus shipping and tax. This is critical information for all homeowners. , 3 Reasons Why Your Ice Maker Isn't Working Thank you Don. State change of refrigerant gas to liquid:The state change of the air conditioning refrigerant from a high pressure high temperature gas back to a liquid occurs inside the outdoor condensing coil. The side facing me borders the patio cement block and the other "3 sides" are in strip of garden space. This is largely related to the fact that energy regulations have commanded that the minimum SEER rating (efficiency rating) be increased over the last few years. A cap tube is simply a small diameter tube used to meter liquid refrigerant from the "high" side of the system into the cooling coil (the start of the low side of the system). Dealin You could cause serious damage. I really do appreciate it and hope that I've been able to provide you with something you'll be able to use. Answer: The good news is its working, but the bad news is it may be tripping a limit due to extreme operating conditions. 2022 The Arena Media Brands, LLC and respective content providers on this website. Thank you for this info, you did a great job here! - Fan or 7/23/11, Fan or compressor: you could also have a bad control board, or relay switch in the compressor/condenser unit. Control circuits and a contactor relay turn on the outside compressor/condenser motor and its outdoor cooling fan as well.The air conditioning or heat pump compressor compresses the incoming refrigerant to a high pressure gas and moves that gas into the condensing coil described just below. Otherwise, I would imagine it can be fixed whatever is the issue but am not positive what that issue is. While diagnosing a circuit or component problem within an air conditioner or heat pump control board is beyond the skill of most homeowners, a simple visual inspection might show you that the control board has been visibly burned, broken, or damaged. Voted up and shared. @oscarlites - I know it can be tough but many of my hubs explain that though this is the case, HVAC supply houses will often help you if you are prepared with the information they need to help you. The labcator cord is cut what are the steps to repair it its the cord the water comes out when my centeral air on. When the thermostat tells the furnace that it wants cooling, the furnace then relays this message to the contactor via a 24V signal. So you're hungry and head to your fridge for som The evaporator coil is really just a box of fins and tubing with a drain attached to carry off the condensation it collects. Keeping Your Air Filter Clean Is Important for the Same Reason. What more can go wrong? The refrigerant gas is thus heat laden with SENSIBLE HEAT (web article explaining sensible heat is heat that we can measure) from the living area and compressor heat from the compressor motor.Low side and high side refer to the low-pressure and high-pressure areas of the air conditioning equipment and are defined in more detail, at SEER RATINGS & OTHER DEFINITIONS where we also explain sensible heat and other air conditioning terms.Refrigeration and Air Conditioning Theory. My wife turned on the a.c. when it still had the cover on it and when I realized it and took of the cover the fan had stoped working. This article is accurate and true to the best of the authors knowledge. , Guide to Buying the Right Thermostat An air conditioning system is rather simple in the number of parts it's made up of. While thats not the common term I can see why someone may call it that. Do you have suggestions block the view without interrupting the functioning. This is also why cut grass, leaves, and "fuzzies" are pulled into the fins on the coils which must be kept clean for good airflow. Let's face it, you have guests JT our link at the ARTICLE INDEX the bottom of this article NOISE AIR CONDITIONER / HEAT PUMP provides noise diagnostics.About taking a long time for the A/C to "come on" when the temperature is set low: the thermostat is operating like an "on-off" switch that turns the air conditioner system on and off in response to room temperature. tipstoretireearly from New York on December 07, 2012: Very helpful. If the fan is bad and the compressor is OK you'll hear the compressor turn on at the start of a cooling cycle, though a bad fan and system overheating could later cause some compressors to turn themselves back off. Gail Sobotkin from South Carolina on August 01, 2012: Excellent article. InspectAPedia tolerates no conflicts of interest. Beyond that, there isn't really a control unless perhaps you have some sort of modulating or communicating the type of unit. I actually knew the answer to the quiz, I actually surprised myself! It sort of works like a battery in the respect that it stores power. Lookds exactly like the one at the top of the page. can anyeone help???? Also see COMPRESSOR / CONDENSER DIAGNOSTIC FAQs, I've a Lennox outside a/c unit. Now as I mentioned, the condenser is the main unit but it cannot operate without help from its friends. Unlike a TEV, a cap tube is fixed in output and cannot be adjusted.State changes of refrigerant are what remove heat: Refrigeration systems rely on two state changes of the refrigerant: gas to liquid, and liquid back to a gas. Amazing - all the things I never knew. Of course the board may look OK and still be damaged. See details at CONTACTOR RELAY DIAGNOSIS & REPAIR Also see A/C - HEAT PUMP CONTROLS & SWITCHESWatch out: Some of our readers report successfully replacing minor electrical components such as switches, relays, and contactors. This state change (gas to liquid) releases energy in the form of heat which is blown into outdoor air (or transferred into water). Would that be fuse or something else . This fan is used to pull air through the coils of the condenser to help cool the refrigerant and compressor as well as displace the heat that is coming off of those parts. What happens when the capacitor is bad but not blow yet? The capacitor's function is rather simple, to provide a boost of electricity to help start or run motors. The AC guys may very well be right that the unit is working correctly though Im sure that answer won't make you happy. What should they look for? I'm so glad to see this glossary of terms. Here we also include links to key articles discussing the indoor components of an air conditioner or heat pump system including the air handler and its controls and the ductwork system. Hi Tom, Contact your local Tempstar dealer and give them the model and serial number and they can special order that in for you. Not so much for the fan motor and compressor. With the air being drawn in by the fan comes all sorts of things that block air and keep our condenser from working as efficiently as it should. Buy one and keep it on hand. I turn the system off for 10 minutes and usually the cold air comes back by the first try.
