So my frigidaire fridge like six weeks ago started freezing. called in a repair company, they got a new thermister (Part Number: 297110400) and a new control board. ( AP5177035 (297326500). said that my fridge is a basic unit and simple, just change out the part. He installed both parts. Needless to say, the fridge didn’t work-fridge turned on, but compressor didn’t kick in. He came back a few days later and said we need to order a new control board. That took another week came back and installed the new control board, it kicked in, compressor worked, but fridge kept freezing. Came back out and said he will order a new part, but that was gonna take another ten days, so I opted to order my own part from Appliance pro to install myself since by then its just a plug in. My part came in first, and it worked for like ten days, but then the fridge started beeping giving a faulty temperature read of 85 and then continued to freeze. I requested a new part from appliance pro, which I received a few days ago. My appiance guy came in the meantime with his part which is also did NOT work! so they were gonna order a fourth part, at that point i said, this is taking too long, I may just buy a new fridge and got some of my repair money back.
Anyway, the new control board from Appliance pro does NOT work. It doesn’t do anything for the fridge. Just turns it on, but doesn’t kick on when the temperature in the fridge is like 50. ao at this point (3 control boards - from appliance company) and two from (appliance pro) are simply not working or fail.
For reference, I did turn off the circuiti breaker of the fridge before installing the parts, then turned the circuit breaker back on.
The newest part from appliance pro didn’t kick in, but when i changed back to the first part from appiance pro, it kicked in but ofcourse it’s not reading the temperature in the fridge.
Could i have five failed control boards from two different vendors?? what else can I try?
Is the light installed on this unit the OEM light or has it been replaced with an alternative? I ask because there are alternatives that have a different current draw from what the manufacturer specs recommend and it can cause a control board to act erratically.
Everything is orignal except for the control board and the thermister. I’m attaching a picture o the board, i installed it into the original “cabinet” that houses the board, and i plugged it into the original cables that came with the fridge also pictured.
What you are suggesting makes sense since five boards didnt work, and one is on and off. any advise on how i can fix that?
For testing purposes, what happens if the LED lights are removed? Also, it appears there is a slight gap in the wire connection near the ceiling. Is there any room for it to push in more?
If you would not mind, would you be able to test from the black wire to the white wire for Volts AC with a multimeter? What voltage reading shows up? Once that is identified, if the power supply cord could be unplugged, the 7-wire connection at the main control disconnected, and the red wire tested for resistance to the black wire. What resistance reading shows up?
The thermistor circuit appears to be good and the voltage is certainly good. Using the control that had the working LEDs but was freezing everything, there should be a model ID displayed for 5 seconds when you first plug the power cord in. What model number does it display?
There is no model number that shows up, i’ve seen those installed multiple times the only thing that shows up is the number 3. Attached is the picture.
we plugged in the part, compressor started, temperature reading in fridge (on control board says high temperature-83), but its really like 55. Fridge kept cooling it reached 42, but fridge kept going, and so we measured the ohms- heres a picture. Does that make any sense?
Thank you for sharing the docs. Upon looking at the termistor document, here is what we found.
Our fridge froze overnight, so it didn’t stop after reaching the desired temp. we measured the resistance with the temperature displayed in the pic-around 24 degrees. that does not line up with the what the attached thermister document states.
When testing the thermistor resistance, the wire connection going to the control board would need to be disconnected. With the control side being connected, there could be a false reading.
Then this reading is done correctly as it is not connected to the board.
My understanding is that for the warrantee to come into effect, i would need to trouble shoot this. .is there anything else we need to do or is this another faulty control board?
If I am reading the measurement correctly, it looks like it is 13.2 Ohms instead of K-Ohms. This would indicate an issue with the thermistor since 13.2 Ohms are going to read a significantly higher temperature than the refrigerator could safely be at. 297110400 Thermistor | Genuine Frigidaire OEM In Stock
the compressor didn’t kick in i waited a good 20 minutes.
