EVALUATION
Incoming power
Check circuit breakers, reset if required. Check power plug to be
supply
sure it is firmly in receptacle. Measure the incoming voltage. Call
power co. if needed.
Power switch
Check continuity between switch terminals. Replace switch as
needed.
Fuse, 10 Amp
Check, replace if necessary.
Fuse holder
Check, replace if necessary.
Fuse, 3 Amp
Check, replace if necessary.
Fuse holder
Check, replace if necessary.
Hi-limit thermostat(s),
Check for voltage on both sides of the switch. Terminals are
control box
normally closed. If open, reset and test oven for proper operation.
If thermostat will not hold, and control box temperature is not
exceeding 140°F (60°C), replace thermostat
Relay, oven power
Check for 120 VAC to the relay coil. If voltage is not present,
Trace wiring back to the hi-limit thermostat. If voltage is present,
check to insure contacts are closing. Check for 120 VAC supplied
to terminal #2 of the relay. If voltage is not present at terminal #2,
trace wiring back to the 10 Amp fuse. Replace relay as needed.
Motor, main fan
Check for opens, shorts or grounds. WITH POWER OFF: turn
fan blade to check for locked rotor.
Capacitor
Check for shorts or grounds. WARNING: Capacitor has a stored
charge, discharge before testing.
Incoming power
Check circuit breakers, reset if required. Check power plug to be
sure it is firmly in receptacle. Call power co. if needed.
Power switch
Check continuity between switch terminals. Replace switch as
needed.
Fuse, 3 Amp
Check, replace if necessary.
Fuse holder
Check, replace if necessary.
Hi-limit thermostat(s),
Check for voltage on both sides of the switch. Terminals are
control box
normally closed. If open, reset and test oven for proper
operation. If thermostat will not hold and control box temperature
is not exceeding 140°F (60°C), replace thermostat.
Cooling fan(s)
120 VAC should now be at the fan motor. If voltage is not
present, trace wiring back to hi-limit thermostat. Check motor for
opens, shorts or grounds. WITH POWER OFF: Check for locked
rotor.
Incoming power
Check circuit breakers, reset if required. Check power plug to be
supply
sure it is firmly in receptacle. Call power co. if required.
Cooling fan
Check the cooling fan thermostat. (thermostat closes at 120°F
thermostat(s)
and opens at 100°F) With the cooling fan thermostat preheated,
check for continuity. If switch is open, replace thermostat.
Fuse, 3 Amp
Check, replace if necessary.
Fuse holder
Check, replace if necessary.
Hi-limit thermostat(s)
Check for voltage on both sides of switch. Terminals are
control box
normally closed. If open, reset and test oven for proper
operation. If thermostat will not hold, and control box
