Customer Questions and Answers for Compressor Run Capacitor by Frigidaire

Zeke, 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. OR 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. OR 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. GROUNDING CHECK 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.
