COMPRESOR IS NOT TURNING ON ON MY FRIGIDAIRE FRS23LH5D WHAT CAN I DO?

yes, but when it is running, does it also turn off??

your relay on compresor is out. check and see if compresor runs

check for compresor operation. relay in compresor can fail at times

your power contactor relay on the compressor body is defective

If you heard the compresor running and it's not cooling ,probably is out of refrigerant(freon) ,but ifthere's power in the outlet and the compresor isn't working and is hot to the touch ,could be the relay or the compresor went bad ,also if there's power but the compresor is cold it could be the thermostat is open ( you can check it by putting a jumper in the thermostat wires).

It could be the condenser coil is dirty , the condenser fan motor burned out or the compresor itself is bad.

That noise is typical when the compresor is trying to start but it doesn't , it could be the condensing fan motor that doesn't work and the compresor goes off on overload ; a common problem with this compresors is the relay (mounted at the side of the compresor behind a black plastic cover) goes bad , this you can replace is about $20 , and if still the compresor won't start you will need to put another one and this is an expensive job.

Set the thermostat to the coldest and check if there's power to the compresor relay , if yes the relay or the compresor are bad (in this case replace the relay which is the cheaper first step ,but if the compresor still won't start probably is burned out) If there isn't power to the compresor put a jumper wire to the thermostat if the compresor runs replace the thermostat.

If the fan located next to the compresor works that means that the compresor relay is bad or the compresor burned out.

All refrigerators compresors have a relay and a overload thermal protector ,both are located on the side of the compresor behind a black plastic cover atached to the compresor with a metal clip(or just the cover snaps in on the compresor).Unplugged the fridge ,pullout the cover and you'll see the relay and the overload replaced them (no more than $30).If this doesn't solve the problem you have a bad compresor, wich is a much more expensive job.
