Correction
LEDs on Burner Touch Board operating properly.
Harness /header pins to Burner Touch Board.
a) Welded relay contacts
b) High resistance in sensor connectors, especially
at sensor in rear
a) Disconnect sensor harness from control.
Measure resistance. Should be ~1100 ohms
at room temperature with 2 ohms per degree
change.
b) Look for damaged harness terminals/pins if
resistance is OK.
Replace board.
a) Probe should be ~10K ohms at room temp.
b) Disconnect jack harness from control. Check
for shorted jack or harness. Center pin may be
touching insulation retainer.
a) Check for shorted J241 pin 2.
b) Replace board.
a) Check LIN wire in harness.
b) Replace RPSM Board.
a) Check LIN wire in harness. b) Replace RPSM
Board. c) Replace Main Logic Board.
a) Check power line for dropouts. b) Replace RPSM.
Replace AUX Board, especially if MAIN Board relays
still function.
Replace AUX Board, especially if MAIN Board
relays still function.
a) Check power line for dropouts. b) Replace RPSM.
a) Harness opened to bridge board.
b) Induction module or bridge board not getting
power.
a) Touch film has a short. b) Main Logic Board fault.
a) Touch film has a short. b) Main Logic Board fault.
a) Harness to J241 pin 4 open.
b) Replace Main Logic Board if voltage is OK
to J241 pin 4. OR
c) Replace Main RPSM Board if no voltage at
RPSM J17 pin 9.
