After turning the unit on, it clicks to start, but then clicks right back off...
I just installed a used Whirlpool ACQ122XK airconditioner, that has been stored for about a year. Anyways, I turned the unit on before I inserted it into its housing unit and it worked just fine. Then I inserted it into the housing unit and ran it for about 10 minutes and it ran fine, but the front radiator looking piece was sort of grimy, so I turned it off and vacuumed it, even though the bottom of it was sort of wet. I did not bend any of the aluminum pieces or anything, but now it won't turn on. When I turn the unit on, the lights come on and it sounds like it is going to start blowing, but then it clicks, behind the "power square" with the on/off switch and the cool/fan speeds, and the blower turns back off. Then about 30 seconds-1 minute, it clicks again, like if the blower is going to come back on, but then it clicks again and turns off. I have tried to unplug it and let it set for 3-5 minutes and try it again, but it does the same thing over. Do I need a new unit or is this a minor problem that can be fixed? Or even a solution, that I can possibly try, that might make it work? Thank you for any help that I can get!!!

Pam, be sure tat the filter is properly installed. Whenever you remove the filter for cleaning, be sure to turn the unit OFF, before removing it. And back ON after it is cleaned and reinstalled.
For the blinking problem. Turn the Master ON/OFF Switch to OFF and unplug the unit for 15 minutes. Once the time has elapsed, plug the unit back in and turn the Master ON/OFF Switch to ON. Hopefully, during that 15 minute timeout, the unit's electronics reset themselves and reverted back to the original factory settings. If so, the filter light should have stopped blinking, if the filter is installed properly.
I hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.
Hi, The motor needs the bearing oiled...to do this you will need to get a bottle of oil at your local HVAC supply house that has a long pull out spout on it... then place a few drops of oil on the shaft by the motor... if possible then tilt the unit so that the oil will run back the shaft and then get the motor to run... the oil will work its self into the bearing...this will lube the bearings and free them up... you will have to do this for both sides of the motor... If the motor has little tubes sticking out also place a few drops of oil in each tube...
This could be caused by an installation problem. The system could be severly overcharged, causing the compressor to load up and can cause a failure. i would start there. Is your intaller qualified to install these systems? (does he know what he is doing?)
I recommend, checking the refrigerant pressures first. You can also check the Polarity of the high voltage in to the outdoor unit. If the compressor is an Inverter Drive compressor, and the polarity is reversed, the compressor can run backwards causing the noise and eventual failure. To correct a polarity problem, simply remove the 2 high voltage wires that feed power to the outdoor unit from the board or contactor. Then reconnect those 2 wires, in the opposite position. (say you take loose from the unit and the Black wire is on the right side, and the white wire is on the left side. Simply swap sides, reconnect the Black wire on the left side, and the White wire on the right side.
Have you checked that the controls are not set to fan only? If you have lets go to the next step. All window A/C have thermal switch.. These thermal switch keeps the compressor from overheating. In the event that the compressor is overloading it would trip then click back on as the compressor cools down. Sometimes those switches go bad but the compressor is ok. They are mounted on the compressor themselves and accesable once the A/C unit cover has been opened.
Either the unit is really dirty or it is low on refrigerant. Difference in voltage is fine. I would suggest that you clean the unit thourghly and then retry. If it doesn't cool and the compressor is kicking on, then its low on refrigerant.
First off, I dont think you caused this problem by vacuuming the unit. It is possible that you did not leave much time before restarts but you then said you tried leaving it off for 5 minutes which should be adequate enough. f you let the unit set for a couple of hours before a restart that should be enough time for the compressor to cool down to ambient temp. I would then try restarting the unit, if it works leave it on for a while and make sure it is producing enough cooling. If there is no change in the situation I would suggest that it would need to come back out of the housing and check that the compressor is receiving voltage to it. It is possible a start capacitor or relay is the cause of the problem. If it started first time I would suggest it is worth having it checked by a professional as it could be the charge or the starting devices. First off though let it completely cool down and try again. Hope this is of some help.
