I would check the fan capacitor first. You can do that with a multimeter with the capacitor test function. I don't think the compressor would affect the fan like that. If anyone worked on the unit before it started running like that you should make sure the capacitor is connected to the start wire and not the run wire. Let me know what you find.

Rheem air conditioner fan not working outside


with the unit off: use a stick or something safe to try to move the fan blades to be sure the motor is not seized. If it spins freely :turn the unit on and use stick to give the fan motor a "boost". if it takes off and runs you have a bad fan capacitor which is the most common cause of your problem

When power is applied to the motor try spinning the fan blade with a small object such as a stick, if this gets the motor going than the capacitor is faulty and must be replaced. The capacitor is located in the outdoor unit.

My Rheem hvac condenser fan shuts off after a few minutes. I've replaced the fan motor and cap. What else should I try?


Does the compressor continue to run or does it cycle off as well? If the compressor is also cycling, it sounds like you are low on refrigerant.

If the fan is cycling off but the compressor continues to run:
(1) make sure the capacitor is wired correctly and is the correct mfd for the motor
(2) make sure the motor is going the proper direction. If it is going backwards the motor could be overheating
* if the direction is wrong, most new motors have a plug with two wires going to it in the end bell of the motor that you unplug and reverse.

Strong burning smell coming from vents and from inside rheem electric central heat. Smells like rubber burning.


You must have to open it, try to clean it..and check for some eletric cables with short circuit or bad cables burning and overheating...check the motor fan and if it has a bad AC capacitor
check the photo, and you will have an idea.v4ndre_0.jpg Good luck!

Very loud buzzing noise when unit is running


Check the contacts of your contactor for signs of overheating. Replace as necessary.
Check the tightness of the reversing valve solenoid coil if you have a reversing valve and tighten as necessary.
Check for the casing vibrating and adjust/tighten as necessary.
Check for any components including refrigerant lines rubbing along casing or bottom of unit.
Check fan blade hub and ensure blade is tight on hub.
You can disconnect the fan motor wires (tape off the leads to prevent short) and run the unit for a minute to see if the vibration exists without the fan motor running.

I hope you find these suggestions to be very helpful moving forward.

How you speed up a fan on a rheem air handler to blow more air in my house


You can change the size of the pulleys. Either increase the fan pulley size or lower the motor pulley size. Don't go more than 1 inch at a time. You will also have to change the length of the belt. The motor runs at 1725 rpm's.
