*
Replace or repair it if relay on sub PCB or
main have a short circuit .
*
Check whether harness has been
misconnected or have a short circuit .
*
Replace or repair harness .
*
Measure resistance values of each
heater are within a normal extent or
not .
*
Replace heater is in a abnormal state .
The self-cleaning
feature will not
operate when
warming center or
warming drawer
is on .
*
This is in normal state .
