my self-defrosting (Fridgedair - upright and side by side)
fridge is freezing up on a weekly cycle. If i defrost the
**cooling coils** in the freezer manually on Monday the coils are
frozen/frosted up by the following Monday... essentially blocking
the cold air from going to the refridgerator side.

When i manually defrosted i measured the resistance of the heater
element going around the cooling coils at 19.2 Ohms ?

What could be possible conditions to cause such a problem ?

what sort of components or actions should i be doing to repair ?

helpful advice greatly appreciated.

Robb,

the defrost cycle is controlled by a timer. When the timer fails the
defrost cycle does not start. Your timer may have failed.


there is also usually a defrost thermostat that turns off the heater
when the temp at the thermostat reaches a point above freezing. If the
thermostat is open, the heater never gets power, and it ices up.
