ISSUE
F2: Cook Temperature
Low
RESOLUTION
1. Verify the high-limit thermostat is not tripped.
If high-limit is tripped, reset and allow the oven to warm up.
If high-limit is not tripped, follow the instructions below.
High-limit thermostat is not tripped.
Place a small water load in a microwave/heat-resistant container
(approx. 275 ml) in the oven and place the oven in
the key to actuate the microwave. While holding down the
MGTRON
key, watch the CC and IR temperatures. If either temperature
MGTRON
bounces substantially, there may be a noise (EMI) problem.
To correct this problem, examine the wire routing for each
thermocouple wire. If the wires are routed near any high voltage
components such as the magnetron or high voltage transformers, re-
route the wires. If this does not correct the problem, verify that both
magnetrons are securely mounted. Call Technical Support for further
