I have a GMP series air conditioning unit. The compressor kicks on but the inside fan does not come on. Have replaced the capacitor to no effect. The fan turns freely by hand. I can hear the relays on the circuit board click, but the fan will not run. Even when I put the thermostat setting to run, the fan will not turn. Can you help with this?

    The blinking light on my circuit board is blinking (pulsing) at a normal pulse. There are four wires connected to the circuit board and two to the capacitor. Which wire am I suppose to ohm out to check the motor?

    Is the fuse on the circuit board good?

    The air handler circuit board has a common terminal. It also has a green wire connection for fan. With the t-stat set for heat or cool do you read 24v ac at the common and green terminals?

    What are the wire colors to the fan motor?

    The brown and brown with white stripe go to the capacitor. What other colors do you have and what terminals are they connected to?

Hi there,

When a fan malfunctions, the problem is usually loose or dirty blades. If the fan won't operate or if it's noisy, cleaning and tightening will usually fix it. Here's how to repair a room air conditioner's fan:


  1. Open cabinet and locate fan.
  2. Clean away any debris with vacuum and soft cloth.
  3. Check fan blade on motor shaft for looseness. Blade is fastened to shaft with setscrew at hub of blade.
  4. Tighten setscrew with screwdriver or Allen wrench. If air conditioner has round vent fan, tighten fan on motor shaft by inserting long-blade screwdriver through port in fan.
  5. Fan is installed in its h­ousing with bolts, and vibration can loosen these fasteners. Then tighten them with wrench.
  6. If fan has oil ports, apply several drops of 20-weight nondetergent motor oil (not all-purpose oil) to each port at beginning of cooling season.
  7. If you suspect fan motor is faulty, test it with VOM set to RX1 scale. Disconnect terminal wires from terminals, and clip probes of VOM to wires.
  8. If meter reads between about 3 and 30 ohms, motor is functioning properly. If meter reads either zero or an extremely high number, replace motor.
  9. To remove the fan motor, remove the fan, the power wires, and several mounting bolts. Install the new motor with the reverse procedure. However, if the condenser coil must be moved to get the fan out, do not try to remove the motor. Call a professional service person.

I have a Frigidaire gallery series fridge. The fan runs all the time and rarely turns off. The condenser kicks off and on normally and it's maintaining temperature but I don't know what it's causing the...


Hi Brandy,

As for your fans, the fans in the back of the unit, (bottom back of the unit, not inside) is called a condenser fan motor this only cools the compressor for the fridge. This fan only runs when the compressor is running. The other fan is in the freezer section and is a variable speed fans motor, this can do two different things with only one job. The fan itself can ramp up and down in speed to control air flow and temperature demand in the two sections. This can run a lot but should slow down when temperature is met or while in a defrost mode. So to sum up this answer, it is common to hear fans run in the newer unit over the older units. Believe it or not do save energy with just moving air over running the compressor all the time.

I hope this helps.

I have a 1994 bmw 525i series it is over heating with a new waterpump and thermostat


Suspect #1 - air in cooling system. These can require several bleeding attempts to get all the air out. If the overflow reservoir is old and cracked inside, it will keep getting air back into the system.
Suspect #2 - radiator plugged internally with mineral deposits from hard water or silicates from using the wrong coolant. Does the radiator feel hot all over when the car is hot?
Suspect #3 - radiator plugged externally with organic material or the hair from the long haired cat that sleeps in your garage. Put a light behind the radiator and see how well you can see through it from the front grill.
Suspect #4 - failed fan clutch and/or failed electric fan. Does the overheating happen on the highway, or only when stopped or moving slowly? Does the electric fan kick on whenever the air conditioning compressor kicks on? The most common failure point on the electric fan is the relay.
A defective new thermostat is possible but unlikely.

Room a/c works great for hours and then compressor just stops


the unit may be knocking off on defrost if the coil is getting v cold,

check for full airflow over the indoor unit/evaporator coil, check filters fan operation and coil condition. Likewise it may be overheating so check the same on the outdoor unit/condenser clean coil and fan operation.

Unlikely but the unit may be under performing and slightly short on refrigerant, not providing enough suction cooling to the compressor motor so the internal over temp klixon would cut it off for short periods, to cool the motor.

Compressor appears to kick in, runs for short time


It sounds like your unit may have a bad run capacitor or start capacitor and relay. Low voltage will also cause this problem. First you need to make sure that you have the full rated voltages at the unit, if you do, then, have the run and start capacitors checked out and the start relay.

I turn it on (montana 5th wheel) and it sounds like it's tryin to kick in the compresor that is and the fan comes on and the compressor tries to kick in about every 30 seconds but cannot?? it's about 4...


The compressor is trying to start and cannot because it is broken inside and will need to be replaced. The compressor can be replaced by most anyone that is familiar with working on home central air conditioning units. I have replaced a few compressors for units like yours. Have a professional check it out. It could just be the start capacitor, but usually it is not.

During air condition mode fan does not run unit freezes up and there is a red flashing light on the circuit control board. The board # is GMP 125-5. The outside compressor work normally.


Dear tomsandi,
Either the fan motor is burnt out or it is not getting the power supply, hence the fan is not working. Since there is no air passing through the evaporator the cooling is not taken off fron the coil so it freezes. The fan motor has to checked up.

COMPRESSORS HAVE AN INTERNAL T-STAT TO PROTECT THE WINDINGS ... SOME THING IS CAUSING YOUR COMPRESSOR TO RUN "HOT" THIS WILL KICK "IN & OUT" THE COMPRESSOR DURING COLLING OPERATION AND HEAT MODE (IF IT IS A HEAT-PUMP). 1ST THING TO EASILY CHECK IS THE CONDENSOR "OUT-SIDE" COIL. (CLEN BOTH WHILE YOU ARE AT IT). THESE FANS PULL THE AIR IN AND A BLOW OUT THE COIL .... ALL THE DIRT WILL BE ON THE INSIDE. 2ND THING IS THE FAN ITSEL OVER HEATING AN TURNING "OFF" ON ITS OWN "BUILT-IN POTECTION T-STAT". THIS WILL GIVE YOU THE IRRATIC OPERATION YOU ARE DESCRIBEING. I TEND TO THINK IT IS YOUR FAN MOTOR ... EASY TEST. TURN "OFF" EVERYTHING BUT THE FAN. SET IT FOR MANUAL "RUN ALL THE TIME" POSITION. THE FAN SHOULD NOT KICK OFF !!! IF IT DOES YOU FOUND THE PROBLEM. IF IT DOES TURN OFF IT CAN BE A WEAK CAPACITOR. UNITS VARY ON WETHER THE CAPACITOR IS FOR COMPRESSOR/FAN OR HAS A SEPERATE CAPACITOR FOR EACH. CAPACITORS ARE NOT EXPENSIVE. HOPE THAT CAN NARROW YOUR PROBLEM DOWN
