Thermal Cutout 

Disconnect all wires from TCO. 
Measure resistance across terminals.

Diode/Rectifier 

Discharge Capacitor 

 

Remove diode lead from capacitor and 
connect ohmmeter. 

 

Reverse leads for second test. 

Infinite resistance should be measured in 
one direction and 50KΩ or more in the 
opposite direction. 

 

NOTE: 

Test meter must contain a 

battery of 6 volts minimum. 

 

 

Capacitor 

Discharge Capacitor 

 

Remove wires from capacitor terminals and 
connect ohmmeter, set on highest 
resistance scale to terminals. 

 
 

 

Also check between each terminal and 
capacitor case. 

 

   1.05uf 

 
Between Terminals: 

Meter should 

momentarily deflect towards zero then 
return to over 5 MΩ. If no deflection 
occurs, or if continuous deflection 
occurs, replace capacitor. 

 

Terminal to Case: 

Infinite resistance. 

 

 

Magnetron 

Discharge Capacitor 

 

Remove wires from magnetron and 
connect ohmmeter to terminals. Also check 
between each terminal and ground. 

2M248(J)A-B2 

Between Terminals: 

Less than 1 Ω. 

 

Each terminal to ground measures 
Infinite resistance. 

NOTE: 

This test is not conclusive. If 

oven does not heat and all other 
components test good replace the 
magnetron and retest. 

 

 

Stirrer Motor 

Remove all wires from terminals.

To avoid risk of electrical shock, personal injury or death, disconnect power to oven and discharge capacitor 
before servicing, unless testing requires power.
