Microprocessor Temperature

Sensor Probe Replacement

Discontinue electrical power to the dryer. Remove perforated panel from tumbler.

Remove microprocessor sensor bracket assembly from dryer.

Disconnect sensor bracket harness connector.

Loosen the 2 Phillips head screws, which secure bracket assembly to dryer and remove bracket from dryer.

NOTE: Do not remove screws.

Disassemble sensor probe from bracket assembly by removing the top push-on fastener securing the probe from bracket. Use a small screwdriver to slowly pry the fastener off.

Disconnect the 2 “orange” wires from the high heat (225º F [107º C]) thermostat, and remove modular bracket connector, wires, and probe from bracket assembly.

Install new sensor probe assembly by reversing procedure. Reestablish electrical power to the dryer.

NOTE: If, when electrical power is reestablished, the microprocessor computer L.E.D. display reads “TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE,” check for a loose connection in the wiring.

To Replace Spark Ignitor and Flame Probe

Discontinue power to the dryer.

Disconnect high voltage connector and flame-probe connection from ignitor.

Disassemble ignitor from burner by removing the 2 self-tapping screws.

Reverse procedure for installing the new ignitor probe.

NOTE: Before reestablishing power to the dryer, visually

check the following: (refer to the illustration).

The flame-probe, ignitor probe, and ground rod are all on the same line of axis.

There should be a 1/8” gap (+/- 1/32) between the ignitor probe and ground rod.

Do not wrap the red high voltage wire and flame-probe wire together. (Improper operation may result.) They may run along side each other.

Hot Surface Ignitor

Discontinue electrical power to the dryer.

Disconnect the hot surface ignitor wires from S1 and ground (GND) on the HSI module.

Disassemble hot surface ignitor probe from burner by removing the one self-tapping screw.

Reverse procedure for installation of new hot surface ignitor.

NOTE: Do not wrap the hot surface ignitor wires and the flame electrode wire together. Improper operation may result. They may run alongside each other.

Reestablish electrical power to the dryer.

Gas Valve Replacement

(Refer to burner illustration on page 11) Discontinue electrical power to the dryer. Close shutoff valves in gas supply line.

Disconnect gas valve wiring.

NOTE: Identify location of each wire for correct reinstallation.

Break union connection before gas valve.

Loosen and remove 4 screws securing pipe brackets to burner.

Remove valve and manifold assembly from dryer.

Remove valve mounting bracket, manifold and piping from gas valve.

Reverse procedure for installing new gas valve.

WARNING: Test all connections for leaks by

!brushing on a soapy water solution.

NEVER TEST FOR LEAKS WITH A FLAME!!!

Main Burner Orifices Replacement

Refer to “To Replace Gas Valve” and follow steps. Unscrew main burner orifices and replace.

NOTE: Use extreme care when removing and replacing orifices. These orifices are made of brass and are easily damaged.

Reverse the removal procedure for reinstalling.
