-BEFORE TO REPLACEMENT INVERTER BOARD - DOUBLE CHECK YOUR COMPRESSOR - Continuity and ground test
The compressor motor for continuity using a multitester. Set the multimeter to the ohms setting X1.Place one probe on any terminal and then touch the other probe to each of the other two terminals. The multitester should display a reading of zero ohms.
Now move the first probe to a different terminal and test the other two terminals with the other probe. Finally, move the first probe to the last terminal and test each of the other terminals with the other probe. Every test should have continuity or low ohms depending on the compressor, with the multimeter displaying zero ohms. If the compressor motor does not pass all of these tests, the compressor will require professional service and new compressor.
Now test the compressor for ground. With the multimeter still set to X1, touch one probe to bare metal on the compressor housing (it may be necessary to scratch away a little paint to expose the metal). Touch the other probe to each of the three terminals in turn.
None of the terminals should have continuity; the multitester should display a reading of infinity. If any of the grounding tests show continuity, the compressor will require professional service and new compressor.
TEST COMPRESSOR BEFORE TO REPLACE THE ITEM
TEST INVERTER BOARD -TEST 1
you have to check the board itself. There are two different tests you can do on the inverter board to see if it's good or not: 1. Check for good input voltages. An Inverter board will have two different input voltages: - 120 VAC main power supply- 4 to 6 VDC control voltage from the main control board (or motherboard- a completely separate circuit board in the refrigerator)
If you're missing one of these voltages, the inverter board can't run the compressor. You'll need to backtrack and find the missing voltage. Could be a bad wire harness connector, bad motherboard, etc. make all voltage measurements with everything CONNECTED. Otherwise, you'll get different readings that could be misleading.
TEST INVERTER BOARD -TEST 2
If you're getting both of these input voltages to the inverter and the compressor isn't running (and you've already checked the compressor winding resistances), then you need to do this next test:
2. Check the current draw on the 120 VAC power supply.
N - Disconnect the 120 VAC power supply from the inverter board.
- Connect your amp meter around one of the wires supplying 120 VAC to the inverter board (doesn't matter which one).
- Reconnect the 120 VAC power supply to the inverter board and watch your amp meter. If the meter stays at 0 amps, the inverter board is broken-- it's not even trying to start the compressor.
If you see the current draw jump to say 4 amps (typical LR current in these inverter compressors) and then drop off, keep watching. Most inverter boards will repeatedly try to power up the compressor. On GE refrigerators, for example, the inverter will try to start the compressor 12 consecutive times. If the compressor fails to start, the inverter will timeout for 8 minutes and then try again. Other manufacturers may have different test schemes but the idea is the same: if the inverter is working properly, you'll
see activity on your amp meter as the inverter tries to do its job.
IMPORTANT Before to replace the the board cleaning the electric contacts of the board, you can use thiner, alcohol or professional contact cleaner with screw driver or scalpel, check every contact in the board.
Spray electric cleaner in the electric contact and terminal
Clean with magnetic screwdriver in the electric contact and terminal
Rinse Electric Cleaner in the electric contact and terminal (homedepot)
