4. If the problem persists, call a qualified Alto-Shaam service technician at 1-800-558-8744.

Check to verify that the high limit switch located at the rear of the unit top has not been
tripped. If it has been tripped, reset by pressing in the hi-limit reset button at the rear
of the oven.
After resetting, the cause of the high limit trip must be corrected. If the high limit switch
will not reset, the high limit switch is defective and must be replaced. This is a safety
device and must not be bypassed or removed from the circuit.
C. To test air sensor:
Test air sensor by placing sensor in ice water bath and using an ohmmeter set on the ohm scale.
The reading should be 100 ohms resistance. If it is more than 2 ohms higher or lower, sensor
needs to be replaced.
