NO BAKE:
λCheck voltage to bake element. Check across relay board at double line relay
λ“no”and BA relay – should get 240V
λCheck Hi-limits SW to see if tripped or double line relay at NO relay
should have 120V
λCheck for open element or broken or open wire
NO BROIL:
λCheck voltage out of BR relay – it should be 120V
λCheck hi-limit switch
λCheck amperage at glow ignitor – should read 3.2-3.5
λCheck safety valve and wires
NO CONVECTON HEAT:
λCheck CVL relay and double relay NO check across and get 240V
λCheck Hi-limit thermostat
λCheck for open element, open wire or bad connection
NO SELF CLEAN:
λCheck volt age to bake element from BA on relayboard and double line relay NO
check across - should get 240V.
λCheck latch to see if locking, check power out of relayboard. Door lock relay
should get 120V
λCheck hi-limit switch
NO CONVECTION FAN:
λCheck voltage out of main relay board at CV relay, should get 120V
λCheck fan blade binding on convection element
λCheck for bad connection, burnt or open wires
NO CLOCK DISPLAY:
λCheck line volt age into unit – should be 240V
λCheck at main relay harness going into ERC at points 14 and 15 for 24 VAC
λIf you have 24 VAC at 14 and 15 – replace clock
λIf no voltage at 14 and 15 - check the two wires to see if they are open. If the wires
are ok - replace the relay board.
