Mike July 03, 2025 for Model Number LGHC2342LF2 I have an inoperative UI display. The compressor and fans work. Cooling to refrigerator and freezer. As display doesnt function neither does the ice maker or water dispenser. The freezer light operates but not the refrigerator light. I have substituted the UI board with no change. I'm left with the Main board or the inverter board but unsure which could cause my issue. I did check voltage to a 3 wire plug at the UI display board and believe it was 4-5 volt range between a couple terminals ( was a bit ago ) I also unplugged the main board connectors and plugged back in with no change. Which board or what test can I do?
1 Answer Mike, If the UI board was replaced and it did not correct the issue then this woiuld be a faulty main control board that would need to be replaced. Read More...
Yana M. April 05, 2025 for Model Number FGHC2331PFCA voltage drop, main board or inverter board is the problem? With Inverter board disconnected, main board sends 5 volts. As soon red and black is connected to main board, 5 volts drops to 0 volts. With Inverter board disconnected, main board sends 5 volts, I put a load on the main board red and black wires, and voltage to 0. So as soon as main board gets a load on 5 volts, it drops to 0 volts. I put another 5volts source to inverter board, no voltage drop, stays 5 volts. Is the main board shorted causing voltage drop when on a load?
1 Answer Yana M., Thank you for your question. Based on the information provided, it could be either board, so you will likely need to replace the inverter board, and if the issue persists, then replace the main board. Read More...
Deb August 25, 2021 for Model Number Model FBPG2277RF2, Serial number 4A61428959 The inverter for our five-year-old Frigidaire went out in a power surge. The repair techs have ordered a replacement TWICE and found the wrong part in the right box. Model FBPG2277RF2, Serial number 4A61428959. Do you have the correct replacement part (CHECK INSIDE THE BOX to be sure). Thanks.
Andrew August 01, 2021 for Model Number FPHN2899LF1 what should the ohms on the compressor windings read mine are 16.5 and all equal. Would this be correct
1 Answer Andrew, The resistance from the common to the start should be around 5 or 6 ohms, the run to common should be about the same and from run to start should equal the total of the other 2 readings. If you have 16.5 across all of them then it sounds like the compressor is faulty and would need to be replaced. Read More...
Raf December 27, 2020 for Model Number EI28BS56IS0 Electrolux model #EI28BS56IS0, it all started with a utility black out for a few hours. Once power came on the fridge came online, I acknowledged alarms but later that evening I noticed by that temps were not dropping @51* fridge and 60* freezer with high temp alarm lit and IQ digital temp display was not reading properly. I called for support and was informed to replace the main board, I did but didn't change anything after a day. I decided to check inverter voltage @120AC & 2.5VDC, then checked compressor @15.8 ohms. I verified freezer fan works, I'm at a loss now, what do you think the issue is?
1 Answer Raf, the inverter 241577505 should receive 12VDC from the main control when the mainboard is calling for cold air to be circulated. As it is not sending the voltage needed, it would be recommended that the thermistors 240597220 are tested from the main control 5303918508. With the power supply cord unplugged, the main control would need to be accessed and the wires at connection J6 will be used for testing. The wire at pin 5 to the wire at pin 6 would be tested for resistance and the refrigerator sensor should measure 19348O at 51°F. The freezer sensor would be tested at the same connection from the wire at pin 1 to the wire at pin 2 and it should measure 15296O at 60°F. Read More...
Lyle December 07, 2020 for Model Number Frigidaire Gallery French Door Does it matter which way the wiring harness goes to the three pin compressor on the replacement part for MCBE2UN? New harness has Brown, Blue, Black. Old had Black, Red, White? Thanks in advance
1 Answer Hello Lyle, this is a 3 phase compressor, all windings are equal, it does not matter how the wire harness to the compressor is oriented. Read More...
Kerry November 09, 2020 My inverter went out with a power surge from the hurricane. Part #MCBE2UN. I ordered the replacement and received #241577505. Will this work? Is this compatible?
1 Answer Kerry, We will need your model number to help you find the right parts for your unit. Please post another question with all your info included thank you. Read More...
Reynaldo November 01, 2020 for Model Number Frigidaire fridge model FGTC2349KS2 I have a Frigidaire fridge model FGTC2349KS2. Freezer and fridge will not cool down. Fridge powers up, condenser fan comes on, but compressor has no start up and does not run (compressor is quiet, no activity). What should the voltage be on the red and black wire going to the inverter (P/N 241577505) ? I am getting 4.0 Vdc coming off the red and black wire (before it goes into the inverter).
1 Answer Hello Reynaldo, the compressor's inverter board is getting the correct run signal (4vdc), using a multimeter check the compressor's windings, they should all match,with no open/short/ground, if ok then replace the inverter board.241577505. Read More...
William September 25, 2020 for Model Number FGHG2366PF0 FGHG2366PF0 { fridge is a 2014 model } Hello, It started with the SY/EF code, and noticed the fridge section was not cold but the freezer was maintaining itself? So I researched and found it was likely the evaporator fan motor, I emptied the fridge, unplugged it waiting for the fan motor. I changed that part out, wasn't difficult, but after getting that all done, the fridge won't start , I don't hear the compressor at all, and the condenser fan motor moves for a split second then stops when I 1st plug the fridge into the outlet, I also get the hi temp warning beep on the panel. The temp says HI/HI, oddly enough I also had seen NP/NP on the display briefly. Took it all apart again, to check it all out but there's not much to replacing this fan motor. Unless the original fan was fine and it's something else ? I also wanted to know if it was possible to take out my ice maker,I took it out temporarily to swap out the fan motor. Just wasn't sure if I could take that out and leave it out for good ? thanks, William
1 Answer William, it would be recommended that the main control 241996361 is tested to identify if it is receiving a full 120VAC. If it is, then the most likely failure would be the main control based on the information provided. Read More...
Joe August 10, 2020 for Model Number phsc39egsso How many volts are supposed to be going to the inverter (black and red wire) from the main board? I know the newer models are 4-6 dcv. Are the older fridges less dc voltage, 2-5 dcv?
