Rheem condenser fan problems

The fan on the condenser outside will sometimes become very loud and other times it will not stop running (loudly) even when the air handler is off. Now my method to "fix" it has been to just give the top of the fan a bop with the old fist, if the handler is running the fan will stop making the loud noise and run as normal, if the handler is not running and i hit it, it shuts off and runs as normal on next start. Do i need a new fan or is it a deeper issue such as a contactor. 8 year old rheem unit, if you need details i will happily post. Thank you in advance for any help.

Welcome to the forums.

You'll need to check and see if that is a single or dual contact contactor.
It sounds like it's a single contact model and the fan motor may have a shorted winding.
If the contactor was bad it would keep the compressor running too.

A model number of the air handler would be helpful.

model number

Thank you for the reply and kind welcome. The air handler model number is RHSA-HM4221JA and the compressor is model number 13AJA42A01. I can't tell if the compressor is running as the fan is so loud when this occurs, If you need pics or for me to make any checks with multi meter please tell me what to check if you could. Was hoping i could just replace the fan motor but i suppose putting in a new contactor is within my ability, it is just replacing the correct one with the correct part number. I will wait for your advice or anymore questions you mat have, thank you so much.

Your condensor uses a single contactor. That means that one side of the motor is always live and if it had a shorted winding it would keep running.

To see if the compressor is running..... feel the larger(usually insulated) copper line coming out of the back of the condensor to see if it''s cold.

It certainly does sound like you have a defective fan motor.
Motor part number should be 51 23053 11.
Order the capacitor for the replacement motor based on its requirements.

Confirm with the place where you buy it that it is the correct motor.

That was it!

Replaced the motor and the contactor switch, running smooth as ever. Your part numbers were also correct. Thank you for your help!!
