Having problems with your Air Conditioners ?

I have an amana package system heat pump model number phb30c02e , sometimes the indoor blower will not kick on thus making no air come in the home at all throught the vents, i tried a new copasitor and the relay and dont think the motor itself is bad but am not completly sure , what else could be wrong to cause that or is there nothing else. any help will be greatly appreciated

Answers :

Sometimes the thermostat can have a burnt place in the fan contacts. This stops the interior fan motor because the compressor wiring is not interconnected to the interior fan. The compressor command is the yellow wire. The interior fan command arrives from the thermostat on the green wire. Check the green wire for delivering 24 volts AC to the fan relay.
\015\012During heat, the heat is electrically interconnected with the interior fan. Thus, if the thermostat is bad, the fan will work properly during heating. I know July is a bad time to turn the heat on, but this is a method to see if the interior fan works properly and is not getting the proper command during cooling.

Dometic said one of the relays was welded or burnt out or closed which is causing the problem. unit works just doesnt stop humming when turned off .Not likely two bad control boards?? Mod.9597.....

Not likely but possible. if they already had one bad board what's to say their production methods have changed since they made your last bad board. I have just had 6 bad compressors from this chinese company danfoss in one month! for only 2 freezers ... Dometic Rooftop RV Air Conditioner

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

Amana PTAC (PTC153B35AM). Unit has simply stopped working. Power is fine from wall to capacitor and control board (but I don't know how to check other leads off of capacitor or board). There is no response from the buttons, nor does the system light even come on. There is a very slight hum when the unit is recieveing power (I think from the capacitor, but I am not completely certain). But nothing else -- resetting breaker on plug doesn't work, nor does switching off/then on the internal

I have a remote comfort control with 3308448.004 relay board. Press Heat button to turn unit on and it does NOT turn on. Have 115VAC to the relay board and have 12VDC to remote control reciever. Sounds like the remote control reciever is bad?? Can I switch my system to the "wired" control system without changing the relay board? I assume it is possible that the relay board is also bad. Is this a common fault with these units?

A Nordyne air handler, model B3BV-030K, with 4 wire thermostat. Thermostat and AC works fine in "cool". Switch it to "heat" and nothing happens.No fan, no heat.(I have built in heat strips -resistors). I jumpered (on the nordyne circuit board-input from thermostat) from R to W. (24 volts from R to W, which should start the heater. Nothing. No relay "click" like when AC comes on. If i jumper R to Y, AC comes on ok. Does this sound like a relay gone bad on the circuit board? Or what? If relay bad,

Air Handler: I have two 24V supply lines one from the transformer the other, I think from the condenser fan. Both wires are connected to a relay which operates the indoor blower. When the 240V power supply is turned on I get a buzzing sound from the relay. Can anyone help me with this problem. Mickey

You have 24 volts from the indoor thermo to the transformer in the air handler then 24volts from air handler to the contactor when this is energized it goes to 240 volts to run the compressor and outdoor fan. Sounds like the contactor is not enegizi ... Air Conditioners

I have a Trane XE 1100 Heat Pump. It is not cooling. My air handler blower works. The outside fan does not. I changed out both capacitors. When you turn unit on you can hear the relay activate. Then only a hum. Is the fan motor bad or the relay? How do i test? The light on the module blinks once a second which is normal operation. Thanks

Probablly the fan. Do this test. Move the fan side to side. and up and down. Any more than 1000ths inch play and that motor is bad. When the bearing gets thin the rotor will rub the stator and lock up. This is called polling out. If the motor is stif ... Air Conditioners

Need help for Toyostove vented heater- Laser 56MH heater comes on when thermostat sensor calls for heat. It brings room up to correct set temperature and begins normal shut down. But here is the problem...the circulation fan stops and I think the blower moter stops? But fire remains in the burner chamber and a moter is quitely running...I think it is the exhaust? The only way it will completely shut down is when I turn back the temperature selection 10 degrees. It immediatly shuts down. Then

Trying to determine whether I have a bad Ign/Lockout or inducer relay board on Mod 58SXA080-GG. If I shut off heat at t-stat or unplug ign mod. for 10 min. It will usually intiate a heat cycle but I only get inducer blower for 10 sec, no pilot, no spark. Then shuts down. Will not auto retry (normal?), I have to remove power. I do have 24V going to relay board when cycle starts but drops out when motor stops (I assume this is the ign module lock out). I checked the air switch by ohming out while

The inducer blower will put a vacuum on your pressure switch which in turn will tell the board to apply power to the ignitor.
