Tracing Limiter Faults - Fisher & Paykel DCS WOSV230 Service Manual

7.14 Tracing Limiter Faults

PROCEDURE:
1. Visually check if the thermal limiter is tripped. If it is "open", the orange tab on the body of the
limiter will be sticking out.
2. Push the orange tab "in" to reset it. Refer to Section 4.16 on pg. 17.
3. Trace the component that is most likely to have caused the thermal limiter to trip
To trace the likely cause of tripping
1. Enter technician mode to help determine the likely faulty component
2. Trace the component fault (top/bottom cavity)
Note: Thermal limiters are positioned in specific areas to detect certain components failing.
These are the most likely causes of a thermal limiter tripping:
Power failure/"cut off" during a self-clean/cooking cycle
Faulty cooling fan (stopped running)
Faulty element/power board (element run-away)
Faulty temperature sensor (incorrect reading)
Refer to the following fault trees for diagnostic information.
