How can I tell if the capacitor on my compressor is bad and if so can it be ohm out?
Answer Hello Rodney. When testing the capacitor, you should get a spike of resistance and the go back to open. If it does this, then the capacitor is good. Hope this helps.

Part# 218909901 would this part keep the refridgirator from coming on and the light not to work
Answer Hello Patricia. No, it would not prevent the light from working. You need to look at the breaker or a wiring issue in the unit.
the controller was smoking so unplugged the freezer need another controller /compressor run capacitor .how do I know if the compressor is damaged
Here is how to check the compressor to test to see if it is faulty.
Obtain an ohmmeter from your local store. We will be doing RESISTANCE checks. This is the safest way because the refrigerator is unplugged from the power source and avoids the possibility of receiving an electrical shock.
Step 1 Set the ohmmeter scale to the lowest ohms setting and ZERO the meter. See the instructions that came with your ohmmeter.
Step 2 Remove one wire at a time, carefully labeling each wire according to the terminal marking on the compressor. This procedure should assure that the right wire is reconnected to the right terminal after checking or replacing.
Step 3 Touch and hold one ohmmeter probe to the C (common) terminal.
Step 4 Touch the other ohmmeter probe to the M (run) terminal.
Step 5 The ohmmeter should show a reading between 1-10 ohms on the ohms scale. If not, the compressor is bad and needs replacing.
Step 6 Touch and hold one ohmmeter probe to the C (common) terminal.
Step 7 Touch the other ohmmeter probe to the S (start) terminal.
Step 8 The ohmmeter should show a reading between 1-10 ohms on the ohms scale. If not, the compressor is bad and needs replacing.
Step 9 Touch and hold one ohmmeter probe to the M (run) terminal.
Step 10 Touch the other ohmmeter probe to the S (start) terminal.
Step 11 The ohmmeter should show a reading between 1-10 ohms on the ohms scale. If not, the compressor is bad and needs replacing.
Step 12 Touch and hold one ohmmeter probe to the compressor housing.
Step 13 One at a time, touch the other ohmmeter probe to terminals C (common), M (run), and S (start).
Step 14 The ohmmeter should show an open circuit when each of these terminals are touched. If not, the compressor is bad and needs replacing.
Step 15 Reconnect the wires to the proper terminals as previously marked.
Thanks I found the controller was burnt on one side. Would I have to replace the run capacitor also?
Answer Hello Tony. No, the capacitor should be fine on the unit. Just replace the starter on the side of the compressor.
It smells like the run capacitor or compressor controller is burning?
Answer Hello Tony. You will need to remove the cover off the side of the compressor and check to see if the starter is burnt and needs to be replaced.
Pulled out the run capacitor and measured the resistance. I am reading 8M ohms and -3M ohms when I switch the leads. Does this mean the capacitor is bad since I do see an open when I switch the leads. Thanks in advance.
When measuring resistance on a capacitor, the resistance will fall until it hits zero. More than likely the run capacitor is good and the start relay would be the most likely cause if the compressor is not running.
