SYMPTOM POSSIBLE CAUSE EVALUATION
Oven fan will not run Incoming power supply Check circuit breakers. Reset if required. Call
power co. if needed.
Fuses, 10 Amp, motor and
controls
Check, replace if necessary.
Fuse holder Check, replace if necessary.
Hi-limit thermostat,
Oven cavity
Terminals are normally closed. If open, reset
thermostat and retest. If thermostat will not hold
for maximum oven temperature, and oven is not
exceeding temperature setting, check for proper
location of capillary bulb in its spring holder. If the
capillary checks okay, replace the hi-limit
thermostat.
Switch, main power Check continuity between switch terminals.
Replace switch as needed.
Relay, oven start Check for 120VAC supplied to coil of relay. If no
voltage is present, trace wiring back to main
power switch. If voltage is present, check for pull
in of relay contacts. Replace relay as needed.
20 minute time delay Check for 120VAC at terminal #1 to neutral on
time delay relay. If voltage is not present, trace
wiring back to 10A. fuse. If voltage is present at
terminal #1, check for 120VAC at terminal #2 to
neutral. If no voltage is present, and oven start
relay is closed, replace 20 minute time delay relay.
Relay, main fan Check for 120VAC to coil of main fan relay. If no
voltage is present, trace wiring back to 20 minute
time delay relay. If voltage is present, check to
insure that relay contacts are closing. Replace
relay as needed.
Main fan motor Check for supply voltage at motor. If no voltage is
present, trace
wiring back to main fan relay.
WITH POWER OFF: Check for opens, shorts or
grounds. Turn fan blade to check for locked rotor.
Capacitor Check for shorts or grounds.
WARNING: Capacitor has a stored charge,
discharge before testing.
No main fan cool down 20 Minute time delay Check for 120VAC at terminal #2 to neutral while
the oven is ‘on’. Turn off the main fan switch,
120VAC should continue to be present for 20
minutes. If voltage is not present for approx. 20
minutes, replace the 20 minute time delay.
