Sounds like you have a bad thermostat. If you pull the face of the thermostat off, you should see colored wiring. With the thermostat set on High/Cool, check the yellow for power, 12VDC. This is the compressor feed. Also, check the Grey wire on the tstat. This is the high fan feed. If you have power at both, then the problem is probably in the relay board. If you do not have power at both, then you need to replace the tstat.

Hope this helps,

Jeff

Radiator fan not spinning


The radiator cooling fan will not start until the engine reaches operating temp OR you have the air conditioning turned on. You may have a bad relay or a bad fan, or a bad temperature switch. You can eliminate the fan by turning on the A/C. IF the fan turns on, then you are looking at what controls the fan for heat control, which is the temp sensor.

Air condition motor not going on


check to see if the fan is running if not it has frozen up over the winter. turn off fuses to a/c unit then try to turn fan by hand,if not soak down fan bearings with penetrating oil like PB Blaster keepmoving fan blade back and forth until it spins freely. Then try turning on the power to a/c unit if motor then turns fan freely , shut it down again and use a good coat of a-1 motor oil (ELECTRICAL) on the fan brgs. This should get you through for another year or so. On the other hand if fan will not spin by the motor now but spins by hand then the fan motor is bad.

In Fan mode, fan works; but in AC mode, I can hear the normal AC sounds, except the fan never turns on. This is the fan in the lower half of the unit in the inside of the house, which blows the air...


on a call for air conditioning your therrmastat brings the indoor fan on and the out door unit at the same time. Since your fan comes on in "fan" mode, it sounds like you need a thermastat. For temp. cooling just turn your fan switch to "on" and turn system switch to cool and set desired temp. System will cycle off and on but fan will not shut off until fan control is set back to "auto". I suggest replaceing thermastat

Furnace runs for about 1-2 min to heat when time for fan stage.. shuts down


the fan may need replacing it may be faulty, but on the ither hand how long since furnace serviced it may be over temping before fan kicks in which means needs the air flow looking at! air flow on a majority of heaters is important if you don't have enough the heater will high temp and shut down, but it sounds if it may be the fan itself if the heaters turning off before fan starts it could be because of a faulty sensor or fan motor ceased and not spinning causing it to trip so firstly look at fan and see if you can see why its faulting if it is also i would check your airflow makes sure that clean enough to get good air flow and if ducted heating check the return air to unit and if has filter take out and try running there could be a lot of reasons for this but usually its air flow or fan if you are not electrically minded i would seek a qualified repair agent for furnace

My coleman 7900 furnace blower cycles on and off while burner continues to operate


I would look at fan limit switch. They are normally located in electrical cotrol compartment. If your are lucky you will have one thats adjustable. It would helpful if I knew is your home a mobile or modular home as they usually use a button type limit on fan and hi limit. It sounds to me like you may be having problems with fan limit which controls temp. that fan comes on . Often what happens is that switch scenses temp to turn on and then draws cold enough air on return air to shut back down until temp.rises again.If this occurs when unit first comes on or continues after burner shuts off you can get a limit switch with a higher temperature rating or one that has adjustable temperature range. Hope this helps you.Thanks.

It making a humming sound and the fan is going around slow the temp in home is 74 the set temp is 65 so it should not be running what could be the problem ruud upka-035jak is model


If you are running A.C.,and the T-stat is set at 65,and the room temp is 74,the A.C. will run until the temp goes down to about 65 or so.Turn T-stat to 76 and the unit should shut down. Also,check furnace filter for dirt, and check condensor unit coils and see if they are dirty.If condensor coil is dirty it cannot breathe properly. That will cause the compressor, and the blower motor to overheat.Wash cond. coil down with water hose to clean .Start at top of coil and go sideways,slowly going down.

Duo-therm quick cool


Your compressor is trying to restart after it shuts off which is causing a power draw down changing the sound of the fan speed change. Check voltage power supply and insure that the power supply cord is heavy enough to carry the necessary load.
