Whirlpool GB2FHDXWB00 defrost problem

6 posts in this topic

Whirlpool GB2FHDXWB00 bottom freezer refrigerator, 4 years old...... freezer keeps icing over, refrigerator gets warm. Manual defrost through control panel works. Repeat problem. Repair service has defrosted refrigerator, replaced thermostat, replaced freezer thermistor (twice), added section of heating wire from defrost coil to inside of defrost drain tube.

 

Other than the above parts, what else is in the defrost system on this refrigerator? I did not see a separate defrost timer on the wiring diagram. This is getting quite frustrating.

 

I was thinking of replacing the control circuit board when I noticed on the wiring diagram that this refrigerator may have two thermistors, one for the freezer and one for the refrigerator section. Where is the refrigerator thermistor located and how do I access it? For that matter, where is the control board located and how do I access it?

 

It seems to me that since the defrost system appears to work, when manually initiated, that the defrost system components work when commanded "on". Besides the control board, what else might command the defrost system "on"?

 

Also, is there available an actual shop repair manual for this refrigerator?

 

Thank you

It's the control board. These units have been noted for the control boards not initiating the defrost cycle on it's own.

That and the compressor relay sticks on those causing them to run nonstop so they can't defrost properly.

BryanS...thanks for the info. Near as I can tell the compressor is not running all the time. Think I'll try the board. I will the compressor relay in mind for future reference. Again, thanks for your response.

Ivasquez11...thank you for the clarification on the relay location. I was thinking of the relay(s) down at the compressor area.
