Page 22 Diagnostics From The Board Sensor Rods Check from the J25 connecter on the board. Look for approximately 5 VDC. Lay a wet cloth across the rods in the drum. You should see the voltage drop. If you do not see the voltage drop, disconnect power from the dryer. Disconnect the J25 connecter from the board.
Page 23 Diagnostics From The Board LED Light Check from the J11 connecter on the board. Look for approximately 3.8 VDC. If you see the voltage but no light, disconnect power from the dryer. Disconnect the J11 connecter from the board. Set your meter to DIODE setting. With your BLACK LEAD on the RED wire, and your RED LEAD on the BLACK wire, you should read approximately 0.727 if good.
Page 24: Diagnostics From The Board Inlet Thermistor
Diagnostics From The Board Inlet Thermistor Disconnect power from the dryer. Check from the J10 connecter on the board. Disconnect the J10 connecter from the board. Set your meter to Resistance setting. Check resistance between the 2 WHITE wires. Copyright General Electric 2012 12/3/2012...
Page 25: Diagnostics From The Board Outlet Thermistor
Diagnostics From The Board Outlet Thermistor Disconnect power from the dryer. Check from the J10 connecter on the board. Disconnect the J10 connecter from the board. Set your meter to Resistance setting. Check resistance between the 2 BLUE wires. Copyright General Electric 2012 12/3/2012...
Page 26 Diagnostics From The Board Heaters Resistance Reading Disconnect power from the dryer. Check from the J7 to the J2 connecter on the board. Disconnect the J7 connecter from the board. Set your meter to Resistance setting. Check resistance between the BLUE wire on J2 and the WHITE wire on the J7 connecter. Should read approximately 41.9 OHM.
Page 27 Diagnostics From The Board Heaters Voltage Reading Check from the J7 WHITE wire and the J2 BLUE wire connecters on the board to the Orange wires either at the J8 or the J5 connecters. You should read 0 VAC. You should see approximately 240 VAC from any of these wires to the L2 fuse with the unit...
Page 28 Diagnostics From The Board Dead Board If the board is not responding check for voltage through the L1 fuse. If voltage is present there, check voltage from the J8 Orange wire to board neutral on J8 White wire. If no voltage check for an open T-STAT or fuse.
Page 29 Diagnostics From The Board Water Valve Disconnect power to the dryer. Remove the J8 connecter. Check resistance between the J8 Brown wire to the Red wire on the J5 connecter. Should read approximately 550 OHM. If resistance is good, reconnect wires put the dryer in service mode.
Page 30 Diagnostics From The Board Gas Valve Also check between J4 and J2. If relay is closed NO voltage should be present when calling for heat. If it is, replace the board. If voltage is present, disconnect power from the dryer. Check igniter, T-STATs, flame detect, gas valve coils, motor switch, harness and connecters.
Page 31: Diagnostics From The Board Motor Resistance
Diagnostics From The Board Motor Resistance Disconnect power from the dryer. Disconnect the J8 connecter from the board. Set your meter to Resistance setting. Check resistance between the BROWN wire on J8 and the RED wire on the J5 connecter. This will read LOWER THAN the lowest resistance because it is a parallel circuit.
Page 32: Igniter And Flame Viewing
Igniter And Flame Viewing When Servicing The Dryer The igniter function and flame can be seen through a viewer hole located in the base of the dryer. You will need to use a mirror as shown in the figures above. The viewer hole is actually the slot on the bottom of the front panel where the front panel mounts to the base.
