SYMPTOM
POSSIBLE CAUSE
CHECK
REMEDY
Bagels or muffins are
too dark or burnt.
Toaster settings are
incorrect.
1. Reduce toast temperature of both radiant
heaters. (Temperature is decreased by
decreasing power to heaters in increments of
5%.)
2. Reduce toast time.
Change both toast time and
temperature until an
appropriate combination is
reached.
Relay is shorted.
Remove side panel to view relay. When the unit is not
calling for heat, the LED on the relay should not be
lit. Measure the voltage across the output terminals
of the relay. When the LED is not lit, the voltage
should be approximately 208V. When the LED is lit,
the voltage should be nominal.
Replace relay.
Main PCB is failing.
Measure the voltage output at the relay connection at
the main PCB. When the unit is not calling for heat,
there should be no output voltage. When the unit is
calling for heat, the output voltage is 5 VDC.
Replace main PCB.
