[FONT='Calibri','sans-serif']I have a Whirlpool refrigerator model # ER2CHMXPB03 S/N ET0801300. It appears that it is not defrosting properly. The freezer ices over and then the freezer/refrigerator gets warm. If I manually defrost it then it is ok for a couple of days but then the process repeats itself. Can you guide me in the right direction as to what parts I may need (heater , thermostat), their part numbers, and possibly how to check them? I would greatly appreciate your help[/font]

The defrost timer sounds bad check in by the fresh food area and it should be next to the thermostat, use a multi meter and see if your getting a ohms reading.

What should the Ohms be?

Hi.

Locate the defrost timer inside the control panel at the top in the fresh food.
Use the flat screw driver to turn the timer's shaft CW very slowly until the unit stops.
Waite for 10 min than open the freezer and check if the defrost heater came on.
If it's on - replace the timer.
If not - check the defrost thermostat and heater for continuity. The thermostat must be ice cold. If you find any of this parts "open" - replace that part.
