Whirlpool

Age

6-10 years

I am experiencing the same symptoms as I had previously (https://www.applianceblog.com/mainf...-refrigerator-ice-maker-not-making-ice.80050/) however, when I get to the Bi-Metal test 6, I get a code of 01, and the heater is heating a frosty freezer. What would be the next thing to do? I think this means I need to change the Bi-Metal but not sure.

I ran the following self diagnostics:

Service Test - 1 FC thermistor

• The board will check the resistance value of the thermistor and display flashes results on the Temp

Display. (01 = Pass, 02 = Open, 03 = Short)



Service Test - 2 RC thermistor

• The board will check the resistance value of the thermistor and display the results on the Temp

Display (01 = Pass, 02 = Open, 03 = Short)

Service Test - 6 Defrost heater/Bi-metal

• Note: if bi-metal is open, it will need to be by-passed for heater to operate. Heater should be on.

Display will be blank until a valid reading is displayed. (01 = Bi-metal closed, 02 = Bi-metal open)


Confirmed the heating element is in fact Very Hot.

If the defrost heater is on, that means the bi-metal is working fine if it was frosty when you ran that Service Test 6.

Like I mentioned in this thread:

FIXED - Whirlpool Refrigerator WRF736SDAM12 defrost not working

I have a WRF736SDAM12 model refrigerator that will not defrost. Service test #6 consistently shows 02, open, regardless of the temperature, and the coils freeze up. I have replaced the w10514110 evaporator motor, which includes a thermostat, but I never get a closed reading on service test 6...

Since both the defrost thermostat(Bi-Metal) and defrost heater test good, then the only part left is the control board.

Here's the control board for your model:
WPW10589838 Electronic Control Board


Its currently in-stock here:

Whirlpool WPW10589838 Control Board (AP6023259) - AppliancePartsPros.com

This is a refrigerator main control board. It manages and monitors the temperature settings of the appliance, including defrosting and cooling times. If the main control board is damaged or no longer working, the refrigerator or freezer could become too warm or cool, stop defrosting, or no...

The new control board fixed these 2 members units, with this same problem yours is having:

Wait, you already replaced the control board in your other thread, correct?

It shouldn't go bad again so quickly, so I'm puzzled as well now, unless you bought a aftermarket control board, those will go bad quickly.

 

[ToddL]

I did, and it's just long enough to be out of warranty. I bought it via the link you provided and got the 60 dollar credit,

That's very strange it didn't last longer, You can contact RepairClinic and see if they can assist you with another one at cost or less.

Other than that, I don't know what else to suggest, sorry.

 

[ToddL]

I’ll give it a shot. Thanks
