DANGER WARNING

Electrical Shock Hazard Electrical Shock Hazard Only authorized technicians should Disconnect power before servicing. perform diagnostic voltage measurements. Replace all parts and panels before After performing voltage measurements, operating. disconnect power before servicing. Failure to do so can result in death or Failure to follow these instructions can electrical shock. result in death or electrical shock.

Voltage Measurement Safety Information When performing live voltage measurements, you must do the following: I Verify the controls are in the off position so that the appliance does not start when energized. I Allow enough space to perform the voltage measurements without obstructions. I Keep other people a safe distance away from the appliance to prevent potential injury. I Always use the proper testing equipment. I After voltage measurements, always disconnect power before servicing.

IMPORTANT: (ESD) Sensitive Electronics ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.

I Use an antistatic wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance -OR- Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

I Before removing the part from its package, touch the antistatic to a green ground connection point or unpainted metal in the appliance.

I Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

I When repackaging failed electronic control assembly in antistatic bag, observe above instructions.

6 Oven Shutdown Thermal Cutoff (non-resettable)

The oven shutdown thermal cutoff (non-resettable) is located at the back of the oven. It will shut down the elements if the temperature at the back of the oven exceeds component limits.

Verify that the oven shutdown thermal cutoff (non-resettable) is OK. To replace this thermal cutoff (non-resettable): 1. Refer to the following chart for the correct Part Number.

Part Number Opening Temp. Marking (with Black Letters) 4449751 338ºF ± 11.7ºF Red (170ºC ± 6.5ºC) 2. Unplug range or disconnect power. 3. Replace the oven thermal cutoff (non-resettable). 4. Replace all parts and panels before operating. 5. Plug in range or reconnect power.
