terminating a cook cycle and/or reverting to the
Off state. The oven will automatically attempt to
restart every 2 seconds until the fault is cleared.
To clear this fault:
1. Turn the oven on. The blower motor may
restart successfully on its own.
2. Test the blower motor in Test Mode (page 26).
Troubleshooting this fault:
To troubleshoot an F1 Fault, see the diagram
on page 28.
F2: LOW TMP (Cook Temperature Low)
This fault will display if the cook chamber
temperature is more than 84°F (47ºC) below the
set temperature after 5 seconds into a cook cycle.
To clear this fault:
Try cooking again. If the cook chamber
temperature is within 84°F (47ºC) of the set
temperature, the fault will clear.
