TEMPERATURE PROBE TEST (SG4D/SG6D)
WARNING: DISCONNECT (UNPLUG) ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT
SWITCH INDICATING YOU ARE WORKING ON THE CIRCUIT.
The temperature probe used in conjunction with the Solid State Temperature controller is an RTD (resistance
temperature detector) of the Thermistor type. As temperature increases the resistance value decreases.
Test Steps
1. Remove the right side panel as outlined under Cover and Panels in Removal and Replacement of Parts.
2. Place a shielded thermocouple in the geometric center of the oven cavity and determine the temperature
in the oven cavity.
3. Remove the probe lead wires from the solid state temperature controller.
4. Test the probe with an ohmmeter.
A. If the measured resistance values are inside the given tolerance, then the probe is functioning properly.
B. If the measured resistance values are outside the given tolerance, then replace the probe and retest.
1)
Check the oven for proper operation.
5. Reverse Procedure to install.
