Question about Refrigerators
My Haier wasn't defrosting right, ice would build up & the freezer would be fine but the fridge temp not right. After reading lots of posts, defrosting a few times,etc., I took advice & ordered a new defrost timer. (Repair Clinic) They had diagrams that showed where things are. This is everything I did. Unplugged it, cleaned off everything in back, double checked fans were all working, drain pan draining, in freezer took off panels to make sure ALL ice buildup was melted including drain hole. Made sure everything was connected (there is sensor w/clip that could be near or on the condensor coils & it wasn't on - so I made sure it was on) - dried things, put back together. Changed the defrost timer. Plugged back in. Two weeks have gone by and things are just fine! You definitely need to completely defrost the fridge because even if the defrost timer is the problem all the ice built up won't allow the fridge to defrost in the defrost cycle. You'll want a fresh start & it's worth it! I thought we were going to have to buy a new fridge! And my husband is proud that I did the trouble-shooting & repair all by myself! Thanks to all the help I found online!

Have looked at the schematics for this cabinet and am unsure as to the location of both defrost thermostats as unclear on drawings. The purpose of the defrost thermostat is to overide the heater and end the defrost cycle, once the temperature on the evaporator is high enough (normally around 0'C). If you have two then one will probably control the heaters going off and the other may well control the fan, for coming back on. I.E. once the defrost has ended the second sensor will tell the fan when the coil is cold enough to come on, this prevents heat being pushed into the main area after a defrost cycle. If you feel competent enough then I would bypass the heater thermostat temporarily and see if the heaters kick in. The other thing to check is that you have a resistance across the two ends of the defrost heater. In my experience the heater is the most likely to fail, the sensor sometimes fail and the timers rarely fail. The age of your cabinet would suggest the heaters. Please do not leave the sensor bypassed as it performs an essential role. Hope this helps.
