Janitrol Ac Unit Capacitor Is Bad
Most the bottom of this page, we have a real good Youtube Video fabricated by Acservicetech that shows how to troubleshoot an air conditioner if the air conditioner exterior unit of measurement is not turning on.Many thanks to the AC Service Tech Channel!
Problem : This trouble is probably the second most common problem that I see every summer in our HVAC concern. The trouble most of the time is a bad run capacitor. The Air conditioner outdoor unit will not come on. Either the outdoor fan does not run, the compressor does non run, or both the fan and the compressor do non run. Sometimes it can be a contactor trouble. If you lot see that the contacts on the contactor or burnt or not engaged (energized) then yous might either take a contactor problem or a low voltage trouble (not getting 24 volts AC to the contactor). Nosotros sell contactors on the post-obit page: Delight click hither if you would similar to see the contactors we sell.
Solution : Yous probably need a new run capacitor or contactor. We have a really adept air workout troubleshooting YouTube video well-nigh the bottom of this page that ucberk599 produced. This video discusses and shows how to install a new capacitor. Please click here if you lot would like to see the capacitors we sell.
1. I would offset recommend turning your thermostat to Off and so reset your air conditioner's circuit breaker. Nigh of the fourth dimension home air conditioners run on a thirty or 40 amp double pole billow. Always were shoes and do non touch any metallic office of the billow box when resetting a circuit billow. Reset the circuit breaker with two fingers on the breaker handle but. Below grayfurnaceman made a video on how to check to see if there is ability coming from the disconnect box to your air conditioner's contactor. I have seen people have one manus leaning on the breaker box and the other hand resetting the breaker!Do not practise this because you are grounding yourself through the breaker box and if there is a problem with the breaker or box and so yous could go shocked! Even if the breaker looks like it is OK notwithstanding flip the breaker all the style off and dorsum on again. I have had many customers over the years that say their excursion billow is ON and OK, but when I drive to their habitation and reset the breaker the air conditioner starts! I hate to charge them a service call when all I had to do is reset a breaker!
2. You have reset the breaker and the outdoor unit of measurement still does not come on. Yous plow the thermostat dorsum down so the air conditioner is supposed to be running and y'all get back exterior to the unit. You can hear a lilliputian humming audio, sometimes a "Uggg" inside the unit of measurement when power is practical. The "Uggg" is probably the compressor trying to start. You might hear the low voltage contactor humming. You pull the disconnect and disconnect the power to your outdoor air conditioning unit. Please make sure your electrical ability is off earlier working on whatever air-conditioning equipment. You accept the door or cover off your outdoor unit of measurement's control box and find that the contactor is engaged meaning that the contactor is getting low voltage from the thermostat and depression voltage controls. If the contactor is not engaged (contacts not pulled down) then you lot take a low voltage trouble which could be in the thermostat, thermostat wires or your air conditioner's safety controls. On some air conditioners, the manufacturer'south install high and low-pressure safety switches to protect the unit if the pressures get too loftier or likewise low. If your unit is low on refrigerant the depression safety switch will non allow the unit of measurement to come up on. If your unit is real dingy of if the fan motor stops the high-pressure switch will stop the unit until information technology is reset. If your contactor contacts are not engaged then it could be a thermostat or safe control problem. Delight brand sure that the batteries are good if your thermostat uses batteries. I have seen depression batteries cause this trouble.
three. The contactors contacts are closed (engaged). Everything is OK with the contactor. If the contacts of the contactor are burnt you might need a new contactor. Nosotros sell contactors on the following page. Please click here if you want to see the contactors we sell. Now yous accept a await at the capacitor/capacitors and find a bad, swollen run capacitor. If you find that your capacitor is bloated and then yous have found the problem of why your unit of measurement will non run! Congratulations! EPA stopped allowing manufacturers to produce capacitors with cancer-causing PCB's back in the 1990's. Since they stopped assuasive the use of PCB's the capacitors now have a shelf life. Many times I encounter capacitor bug that will not allow the compressor or the fan to come up on . Many times you can conspicuously see that the capacitor is bad considering it is swollen or even blown autonomously with capacitor oil everywhere! Sometimes you volition demand a special meter to test the microfarad (MFD) or (uf) rating. "MFD" and "uf" mean the same. Some capacitors volition accept "MFD" on them and some volition use "uf". Virtually of the fourth dimension you lot tin can tell the capacitor is bad because it is swollen upward. Please meet the pictures beneath for the comparison between a good and bad dual run capacitor. Capacitors are chosen "Dual" because the capacitor helps run both the fan and the compressor. Dual capacitors will have three areas where wires can exist hooked up. The terminals are labeled: Fan, C (Com), and Herm. If you need a new capacitor we sell capacitors on the following page: Please click hither to see all the capacitors we sell index page. You will need to know the MFD rating or uf rating and the voltage rating. This should be clearly visible on the characterization of the capacitor. If you exercise not have a capacitor tester you may exist able to take the capacitor to a local appliance repair parts store and ask them to test it for y'all. We sell a capacitor tester on the following page:Please click here to see the Supco MFD10 capacitor tester nosotros sell. If yous do not know what size capacitor your unit uses you can electronic mail us with your unit'southward model number and we will try to discover out which capacitor your unit uses.
