Thermoelectric Voltage in Milivolts
Oil temperature must be below 380°F (193°C) to perform this check.
5. Connect a known good high limit control into wiring for
the suspect thermocouple and control.
6. Connect electrical power and operate vat. If vat does not
overheat, replace defective control with known good part.
7. If vat overheats, perform more checkouts of other
components (relays, contactors, probes,etc.) and replace the
heating element as the last resort.
Replacement
1. Tag and remove lead wires to module.
2. Using 3/8" socket, remove 2 nuts securing control to panel.
3. Install a new control in reverse order.
