output, replace the mercury contactor.

Intermittent Heating

Thermal/Overload

The main fan motor is equipped with

of motor

internal thermal protection and will

cease to operate if overheating

occurs.  As the motor overheats and

then cools, this will cause the oven to

cycle on and off intermittently.  This

may be caused by improper ventilation

or preventative maintenance.  Also,

most of the problems listed under

“Oven will not heat” can cause

intermittent failure.
