Efren February 26, 2015 for Model Number PSC25MSTASS My compressor is not working, I replaced the inverter but that didn't solve the problem. I checked the inverter (compressor control unit) with a multimeter and it shows no voltage output. I noticed there's a 2-wire connected to the main board (wr49x10147) Is that has something to do with the inverter not having an output voltage? I still hesitant to replace the main circuitboard (wr49x10147). Could this be the problem why my refrigerator is not working. The fan motor is working but not the compressor.
1 Answer Efren, You can't test for voltage out of the inverter unless you have a meter that can read 3-phase, 80 to 230 VAC power. However you can check the low voltages at the inverter. The red and white wires are from the J15 connector from the main control board and supplies -4 to 6 volts DC to the inverter, when the sensors call for the cooling to occur. The black and orange wires to the inverter are L1 power and neutral to the inverter, you should have a constant 120 VAC across these wires. Check the voltages at the inverter if you have the voltages you'll need to replace the compressor, if you don't have the voltages, check the wiring for damage or breaks and/or replace the main control board.

Jim December 31, 2014 for Model Number FDCS1nbwalss GE Refrigerator Model No. fdcs1nbwalss Problem: bottom freezer stays at a constant 0 degrees. Upper unit not cooling, Upper unit will gradual increases from 37 degrees to 50 degrees over a 12 hour time frame. No air flow from blower. I then recycle power, blower will then open baffles and I have air flow. This is a daily problem. Board assemble wr55x10966 , air tower replaced wr17x12456 and temp sensor replaced. Technician comments: damper intermittent open and closing. Main board intermittently not sending power to evap fan motor . problem not corrected with replacement of parts, HELP I am down $832.00 and all I have is hot air from the TECH
1 Answer Jim You will want to check the thermistors in the unit and make sure that they are good. If the resistance checks bad then replace the sensor. The resistance of the thermistors are as follows. Thermistor Resistance Temperature(°F)Temperature(°C)Resistance in Kilo-Ohms -40 -40 166.8 kO -31 -35 120.5 kO -22 -30 88.0 kO -13 -25 65.0 kO -4 -20 48.4 kO 5 -15 36.4 kO 14 -10 27.6 kO 23 -5 21.0 kO 32 0 16.3 kO 41 5 12.7 kO 50 10 10.0 kO 59 15 7.8 kO 68 20 6.2 kO 77 25 5.0 kO 86 30 4.0 kO 95 35 3.2 kO 104 40 2.6 kO 113 45 2.2 kO 122 50 1.8 kO 131 55 1.5 kO 140 60 1.2 kO Note: To accurately test a thermistor, place the thermistor in a glass of ice water (approximately 33°F) for several minutes and check for approximately 16K O.

Mike R. April 21, 2014 for Model Number GE PSCS5RGXCFSS This is a head scratcher... This is a dual evaporator unit with a 3 way valve. First of all the compressor and evaporators were just replaced on the unit then the unit stopped cooling within 2 days... Checking the main board vdc to the inverter is 6vdc (so its calling for high) the compressor windings ohmed at 7.5 on all 3 pairs and the compressor runs however the evap coils don't get cold at all, the suction line gets slightly cold near the compressor and inlet tube where the capillary enters the freezer evap coil gets mildly cold but no frost. All fans turn both the evap, and condenser. The condenser is room temperature and the compressor is hotter than it should be. I'm leaning towards kinked plumbing or clogged plumbing or not enough Freon or too much Freon or the 3 way valve is not working rite. But I do feel the 3way resetting to home upon plugging in the unit. I have correct voltages for the fans and the thermistors are reading correctly. I haven't as of yet had a change to put gauges on it. Its like all systems go but it just wont cool.
1 Answer Hello Mike. The information you provided sounds like you either have a Freon leak or the unit is restricted. You can put gauges on the system to see if there is a leak or if the unit is drawing into a vacuum and that proves a restriction. Read More...
Bob March 31, 2014 for Model Number PFIC1NFWABV Model: PFIC1NFWABV compressor running 0.4amp. Is this mean that I have a bad compressor? I changed the inverter and still it doesn't work. What shall I do next? Thanks
1 Answer Hello Bob. If there is power coming to the compressor and the compressor does not run, you will need to replace the compressor on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Jmc December 30, 2013 for Model Number ZISS480DRKSS My condenser fan is constantly running, however my compressor is silent, not hot or vibrating and my refrigerator is not cooling properly (freezer 40 deg F and fridge 55 deg F). From what i have read, it can be the compressor, the inverter or the control board. How do I go about figuring out which one has the issue?
1 Answer JMC, To perform the tests and properly diagnose the issue with your refrigerator, you will need a multi meter TJMA-DM1, clamp on amp meter TJMA-600CFA so you can verify the proper voltage, amp draw and wattages for the mother board, inverter and compressor. If you were going to guess, you may want to start at the inverter, it could be a failed circuit, causing the compressor to run at the "low speed" setting and this would cause poor cooling. If you could repost your question(s) and attach a e mail address we could supply you more accurate and illustrated information to help you through the testing procedures. Read More...

Shel August 06, 2013 for Model Number PFCF1NJWABB Compressor is not turning on. Is there a start capacitor that can be replaced? There is no indication that the unit burned out. Also, is there a thermal overload that might have to reset or replaced in this model?
1 Answer Hello Shel. If there is power to the compressor, but it does not run, you may need an inverter WR49X10283. This model does not use a starter or overload, it uses an inverter. Read More...
