TEMPERATURE GAUGE - REPLACEMENT

1.Shut off power at main breaker.

2.Remove control panel top.

3.Disconnect thermocouple from temperature gauge.

4.Remove two (2) mounting bolts and remove temperature gauge.

5.Reassemble in reverse order.

THERMISTOR - REPLACEMENT

1.Shut off power at main breaker.

2.Remove control panel top.

3.Slide thermistor probe out of oven chamber.

NOTE: Remove conveyor and bottom fingers to aid in removal and instaliaticn of thermistor probe.

4.Disconnect wires from back of digital display at terminal strip (location #9-10).

5.Reassemble in reverse order making sure the probe is placed securely in the wire form in the oven chamber.
