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.

 

No control box cooling

 

Incoming Power

 

Check main circuit breakers, reset if required, call power

 

 

 

 

 

 

 

company if needed.

 

 

 

 

Main Fan Switch

 

Check continuity between switch terminals

 

 

 

 

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 present,

 

 

 

 

 

 

 

check motors for shorts or opens. WITH POWER OFF:

 

 

 

 

 

 

 

Check for locked rotor.

 

No automatic control

 

Incoming Power

 

Check circuit breakers, reset if required. Call the power

 

box cooling

 

Supply

 

company if needed.

 

 

 

 

Cooling Fan

 

Check the cooling fan thermostat. (Thermostat closes at

 

 

 

 

Thermostat(s)

 

120°F and opens at 100°F). With the cooling fan thermostat

 

 

 

 

 

 

 

preheated, check for continuity. If switch is open, replace.

 

 

 

 

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.
