Having problems with your Air Conditioners ?
This unit just won't work at night
I had a similar issue with a product but not the same brand. It ended up being one of the many boards on this system even after the manufacturer said that the board that ended up being bad couldn't make the system behave in the way it was. After I replaced the bad board, it worked like a champ. I would recommend replacing the indoor pc board anyway. If that doesn't work, then there has to be something wrong with the wiring in the unit. If your charge is perfect then it wouldn't work even in the day time not just night especially if it were the expansion valve. I'm thinking that the units aren't communicating properly. Hope this helps.

Dometic duo-therm rooftop ac unit motor wont spin unless i jiggle the wires that go into the motor then it works! Trailer sat in a monsooon storm last night. next morning compressor kicks on just fine and motor hums but fan wont spin unless i jiggle the wires? did somethning just get wet and needs to dry out or did it short out my run capicitor? Help?
If you have to jiggle the wires going into the compressor motor to get it going, I would submit that you may very well have a broken wire or otherwise loose connection that is making contact when you jiggle the wires. If all appropriate connections w ... Dometic Rooftop RV Air Conditioner
2 weeks ago one of my units stopped working properly. It got warm during the night even though I heard the unit running. I shut it off and called for repair service. They changed the thermostat and it worked again,until 2 night later same thing. I called another repair service and he found that it needed freon. For the last 2 weeks it has been cooling fine even with Fla.hot temperatures of 85-90 degrees. Last night same problem unit running and not putting out air thru the vents. Shut it off for
Sounds like the coils inside the air handler/furnace are freezing up. likely cause is the freon charge is incorrect (probably undercharged). it may have been correct when the tech did the work but some may have leaked out. it is slightly possible too ... Goodman CLJ36AR42 Air Conditioner
I have a Tempstar 9000 airconditioning unit and while I was weed wacking I accidently cut a wire to the unit. I replaced the wire but now the unit wont turn on and also my furnace blower wont work even in the "on" position. I have a energy saver unit attched to the a/c unit as well. One wire connects to the a/c unit and the other to the energy saver. If I push the connector on the unit with the panel off the unit will run. Cansomeone tell me how to connect those four wires?

Hi, just replaced the capacitor thinking that would solve the problem but it appears it did not. The motor outside would kick on the unit inside would kick on but the blower motor inside works sometimes and wont other times. Basically, the unit will work just fine all day then we notice the house is getting warm, check the inside unit and everything is running fine but the blower motor is not circulating the air. I have a goodman a30-10 unit. I read where some people said the relay could be bad
Turn off the power to the air handler(indoor unit). Remove the access panel. From the motor,trace the wires back to the fan relay. One wire will probably trace back to the incoming power terminal. The other is the fan relay. It could be intermittent ... Air Conditioners

Check the board for a cold soldered joint. If you can move the spade that the line connects to it should be re-soldered. A cold soldered joint can give intermittent service because it can make contact at one time then loose contact by even a change i ... Air Conditioners
Window unit comfort aire rad 121 e wont get cool. fan works, everything works, just wont blow cold air. can system be recharged like a car?
Actually it can be charged like a car "if" it has charging ports which it won't have unless someone has installed them - which would only of happened if the unit had a leak previously. So, to answer your question a window unit can be charged like a ... Air Conditioners

The downstairs ac unit has a pump that pumps the condensation frm the evaporator ( i assume) through a long tube outside. The AC would not kick on and the pump continuously ran. I was told to clear the line on the pump because the ac wont come on if the pump isnt working right. That was the case and I took an air compressor and blew out the line. I poured water in the pump to make sure it was working and did this three times and each time the water did pump outside. But the ac still wont come
Most older units will work regardless of what the condensate pump does. I have cleaned up enough water messes to know.\012The only way to test this is with a meter. You will need to identify the wire that turns on the AC and test it at the ther ... Air Conditioners
I have an Amana RHE30A2B heat pump. I installed a new thermostat, Honeywell, last night and now the coils are not cooling & the unit is blowing hot air. I have double checked all the wiring & everything seems to work as it should. Is there a breaker or fuse on the outside unit that I am not aware of before I call a service man out. We also had an electrical storm last night. It could be a freak thing, but I am still concentrating on the thermostat.

My unit is 4 years old. I always turn it off when I leave for work in the am and turn it back on when I get home in the pm. Last night I turned it on at 7:30pm.
