Question:

Immediately after closing the door is seals tight but within 15 seconds the door looses it's tight seal and the freezer keeps getting large amount of ice/not frost build up inside at the bottom. Is it the seal that needs replacing or something else?

Answer:

Hi Tayor, Thank you for your inquiry. Check around the gasket to see if you have any debris stopping the gasket from making a full seal. You should also check to see if your appliance and your door are still level. If it is not the door will eventually open on its own. However if all of that is alright, you may have to replace your gasket. Good luck with your repair.

Fault in defrost circuit caused ice buid-up, decreased air flow, and elevated temp. Led to a thaw.

After observing defrost timer go into (and out of), defrost cycle, I checked continuity of heating element. Since heater coil was intact (79 Ohms of resistance), I figured the defrost thermostat (aka bi-metal therm.), had to be at fault. The new part ($17.00), proved my suspicions correct. As I sought to determine if everything worked, I had to wait for the temp. to drop below the defrost therm. set point before I would see the heater coil get hot.
To avoid the costly failure in future, I bought a Chaney wireless therometer with two remote sensors. Sensors require lithium batteries. $30.00 for both are a cheap insurance system.
