EVALUATION
Check circuit breakers. Reset if required. Call
power co. if needed.
Check, replace if necessary.
Check, replace if necessary.
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.
Check continuity between switch terminals.
Replace switch as needed.
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.
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.
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.
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.
Check for shorts or grounds.
WARNING: Capacitor has a stored charge,
discharge before testing.
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.
