Ignition System-Checkout
1. If ame is present during “Trial For Ignition” period but the system shuts down, there may be
an improper ground. The entire ignition system is grounded together including the electrode
assembly, the electrode mounting bracket, the burners and the burner bracket. Shutdown can
also occur if for some reason the system isn’t sensing the ame. Check the sensor for damage
and check the connections of the sensor lead.
2. If there is no spark or intermittent spark, check black hi-voltage lead wire for damage or cracks in
insulation. (This lead wire must not be taped or connected to any metal edges along its length to
prevent pinching and arcing. Also, do not bundle this wire with other wires.)
NOTE: Spark gap and electrode location are important. If the electrode is damaged
or mounting is changed the spark gap may not be correct for ignition to
occur. Check for cracks in the ceramic insulator. Replace electrode assembly
if necessary. Also check for carbon or foreign material on the electrodes
and clean if necessary.
Spark Electrode Assembly-Removal
1. Remove electrode cover and disconnect wires to electrodes.
2. Remove two screws to detach electrode assembly.
Gas Valve Removal (shut o manual gas valve to stop gas ow before removing gas control
valve)
1. Disconnect union at gas valve and disconnect wires from gas valve operator coils.
2. Remove right manifold mounting bracket screws and slide manifold to remove from left bracket.
Main Burner Orice Removal
1. Remove manifold and gas valve assembly as above.
2. Using an open end wrench, remove orices from manifold.
Main Burner Removal
1. Remove the 4 screws securing the cover for the burner housing and the one screw mounting the
high limit cover. With the burner housing cover removed, there is complete access to the burner
assemblies.
Recirculation Chamber Inspection
1. Remove Resettable manual overtemp sensor and remove inspection plate in burner chamber
between main burners and rear back panel of dryer.
Cylinder Removal
1. Remove the front panel in front of the cylinder.
2. Remove drive belt, pulley, and key from cylinder shaft.
3. Pull the cylinder from the front of the machine.
Adjustment Of Cylinder Assembly With Front Panel Removed
1. Loosen the two top adjusting bolts and two bottom adjusting nuts and lock nuts holding the
bearing housing to the drive plate.
2. Loosen the four mounting bolts on the side channels.
3. Open the clothes door and insert a 1/4” thick shim at the 3 and 9 o’clock positions and a 1/8”
thick shim at the 6 o’clock position.
4. Tighten the two bottom adjusting nuts and tighten locking nuts.
5. Tighten the bottom right mounting bolt, then the top left mounting bolt. Tighten the remaining
two bolts. (Shim where and if necessary.)
6. Tighten the two top adjusting bolts.
7. Remove all the shims from between the front panel ange and cylinder (3, 6, and 9 o’clock).8.
Spin the cylinder to check for rubbing baes, pressing down hard while rotating. If rubbing is
detected, repeat procedure paying particular attention to placement of shims between bearing
housing and side channels.
Tumbler Through Bolt Access Cover
Remove 4 screws that mount the air ow switch to the back of the dryer. Remove 2 screws that retain
access cover. With access cover removed, tightness on the tumbler through bolts can be checked and
tumbler alignment can be adjusted.
Bearing Housing Removal
After removing cylinder as previously outlined, simply unbolt the bearing housing and remove.
