Note: ERG30’s had a sail switch prior to SN KC1230128. On 6-7-01 the sail switch
was replaced with an automatic reset switch.
PGR30’s unit with a serial level KB0000000 and KA0000000 had a sail switch - those
with a KC0000000 and above have an automatic limit switch.
Here is a list of functional parts that should be working for the bake/broil to light..
Main Relay Board
Cooling blower
Air switch (sail switch)
Dual gas valve
Bake Igniter
All of these elements must be working in order for the bake or broil burner to function.
Brown wire to broil igniter
120 Volts
NO BAKE
1. Check incoming line voltage to the DBL (double line relay) NO side and neutral.
Should have 120 VAC. If no voltage present trace wiring back to terminal block. If
voltage is present go to step 2.
2. Program the unit into Bake or Broil.
Check voltage at the DBL (double line relay) com side to neutral. Should read 120
VAC. If no voltage present replace main relay board. If voltage is present then check
if cooling fan is running. If cooling fan is not running check wiring and cooling fan
motor.If cooling fan is running then check the air switch/sail switch that is mounted to
the cooling fan assy. You must remove cooling fan to gain access to air switch/sail
3. The air switch/sail switch is a NO switch you should have 120 VAC to that switch.
Take a voltage check from one side of the wire to neutral - it should read 120VAC.
