Inconsistent temperatures within the refrigerator

Questions & Answers

For Whirlpool Control Board (Part Number: OEM20679129)

Fred September 19, 2021 for Model Number MZF34X16DW01

Is there any way to check control board have checked thermistors and heating element all seem to be fine. Goes into fast freeze after a few hours stays there. Thank You. Fred

1 Answer

Fred, diagnosing the main control would be done by process of elimination. As the thermistors tested good, the only item left that would control temperature would be the main control W11382529.

Darlene July 19, 2021 for Model Number MZF34X16DW01

Does this part replace the part in my freezer W10683037... does it have 2 plugs plus one ground wire? Or do I need to sway out the board with a new one for this part to work in my freezer?

1 Answer

Darlene, the electronic control W11382529 is the direct replacement for the user main control in the model number provided. It does have two wire connections and a ground wire.

Bruce August 18, 2020 for Model Number WZF34X16DW

Where does the ground wire connect on part W11382529 (control board)? I pulled the old one out and did not see where the connection was. Thank you.

1 Answer

Hello Bruce, The ground wire from W11382529 clips onto the edge of the heat shield to prevent any chance of electrical shock.

Thomas August 06, 2020 for Model Number WZF34X16DW00

Freezer always remains in "Fast Freeze." When it is unplugged and restarted, it will allow temp selection, but always goes to "fast freeze" within a few hours and will not come out of that mode. I've taken the controoler interface out and checked all the connections, but no luck.

1 Answer

Thomas, the control W11382529 activating the fast freeze on its own, this would be an indication of the control failing.

Linda July 28, 2020 for Model Number Wzf34x160w01

The freezer completely thawed, everything inside was room temperature. The Evaporator fan was operating at the time, as was the compressor. There is no compressor fan on this unit. After finding the freezer completely thawed I pushed the temperature control to the coldest setting and now the freezer seems to be cooling again. Is there some some sort of control board that could have done this?

1 Answer

Linda, The control assembly for this unit is W11382529 and would likely be the issue.

Woodie May 23, 2019 for Model Number WZF34X18DW00

Following up on my earlier question.... The freezer defrost thermistor mounted on the evaporator coil reads 2935 ohms at 75F and 8480 ohms at 33F (in Ice water). It is snugly mounted to the evaporator coil just as it was when I first removed it for testing. When the evaporator coil freezes over, the thermistor is coated with ice just like the coil is and yet the heating element that I've shown to be good does not come on. I believe I've now tested everything else but the Freezer Contrl-Box (AP5988907). Is there an other part that could be the problem?

1 Answer

Hello Woodie, since from your testing the freezer defrost thermistor checks within operating specs ,and it is secure to the tubing then likely the problem is with the control box, W11382529, and no other parts are involved.

Woodie May 19, 2019 for Model Number WZF34X18DW00

Why is my upright freezer not defrosting the evaporator coil? The symptom: Freezer fan is running but food is no longer staying frozen. Accessed evaporator coil and found it to be iced up. Removed all ice and restarted freezer. Temperature returns to about 0 to 4 degrees F when at recommended setting. Food stays frozen. Approximately 4 weeks later the freezer has iced up again and food is no longer frozen solid. Freezer is about 4-5 years old. Heating element reads 36.1 ohms. Heats properly when connected directly to house current. Thermistor on evaporator coil reads 2.94 KOhms at 75F, 8.48 KOhms at 33F (ice water) and 20.88 KOhms at 3.2 F (in a different freezer). Thermistor in the food area reads 2.82 KOhms at 75F, 8.66 KOhms at 33F and 21.11 KOhms at 3.2F. Door seal appears to be in excellent shape. Do these parts appear to be working correctly? If they are working as they should, what else can it be? Is there a way I can diagnose a problem with the Freezer Control Box?

1 Answer

Woodie, check the freezer defrost thermistor part [AP6020675,its mounted on the evaporator coil,, it can be checked with a multi meter and has values of 2700 ohms at 75 degrees and about 8000 ohms at 32 degrees (in ice water), also it has to be snug to the tubing otherwise the control board will think in the defrost cycle the evaporator coil is warmer (defrosted ) then it actually is,.

Jill November 21, 2018

My whirlpool upright freezer model# wzf34x18dw00 has ice building up around the fan and drier but not on the evaporator coil. Also my temp control panel keeps changing itself from the recommended setting to the high setting on it own. I was told the control panel may be faulty but I'm not sure if that is causing the ice buildup. The freezer is only 4 years old can you give me any advice on this so I can buy replacement parts. Thank you, Jill Carter

1 Answer

Jill, If there is only ice where the refrigerant lines come into the unit then this would be an issue with the sealed system and will need to have service for this issue.

Arthur November 12, 2018 for Model Number WZF34X18DW00

no lights on the control box, held the temp control button for 3 seconds still no operation. how do i test the control box?

2 Answers

Arthur, you should have voltage going into the control on the black and white wires, if voltage is there, the control is bad and will need to be replaced.

2 Answers

Author, Go to the control and look for connector CN1. Pins 4 and 1 you should have 120 vac. Wire colors are 1 black and 1 white. If your voltage is there then replace the control if no voltage then there is a wiring issue in a splice or cabinet lining.
