Hello all. I posted a thread a few weeks back about a similar problem that I thought had been corrected, but sadly I was wrong. My WRV986FDEM01 started getting up to the mid fifties in the RC section. I disassembled and found evap completely froze up. Ran the diagnostics and everything checked out SAT. Found a similar thread on here and it was his main board. I ordered a main board and replaced it and i thought the problem went away.
Then I noticed the RC fan seemed to be running ALL the time, (i can be really particular about things). Ran diagnostics and it appeared that the damper was bad because the airflow in the upper RC never ceased, but I did here clicking from behind the back panel. This is what I posted the thread on here about. I replaced the damper and checked it before complete reassembly. That is when I realized where the alternate airflow was during the diagnostics and even though the new damper was working properly, I was still getting significant airflow in the upper RC compartment, so I feel that I may have unnecessarily replaced a part.
Anyway, now temps are rising again (high 40s) and I can see frost at the bottom of the evap coil when I pull the drawer inserts out and look. I am near my wits end. There can't be much more to replace? The fan works great I know that for a fact, the only thing I can see is a thermistor? I figure that replacing the thermistor will be much cheaper than calling a repair person at this point since I already did the main board. My only question is how does the RC evap coil defrost? The freezer has a defrost heater, but the RC does not, so I am not sure how it defrosts. Also, the diagnostics show the thermistor is fine, so that confuses me. I hope that somebody can please provide some insight. Thanks in advance any help you may provide.
