FIXED DRSR495EG8WW GE Dryer doesnt shut off in auto mode

GE

Age

6-10 years

I have a GE Dryer DRSR495EG8WW that has started to fail to shut off in auto/sensing mode. The timer moves and shuts off fine in timed mode, but the timer does not seem to move in auto mode. The dryer gets to normal heat and dries in normal time. Vent is clear.

I was going to start with the dryness control(?) board and go from there, but figured I should check here first. I checked the wetness sensors and they look clean.

Thanks in advance.

Edit: just found this thread with some symptoms and similar model, fixed with control board. Will try that first unless anyone thinks otherwise.

FIXED - DRSR495EG6WW GE Dryer will not stop on Automatic

Hello, I have a DRSR495EG6WW dryer that will no longer turn itself off when using the automatic settings. If I use the timer, the knob will still spin down so it's not completely non-functional. I opened up the control panel and looked at the control board, I did not see any noticeable damage...

If you still have your tech sheet and wire diagram, can you post a copy here? GE usually keeps the same basic wiring for the major components so look on the timer for "T" and "X" and check for continuity between them. If you have inlet and outlet thermistors, check them for about 9000 Ω at room temp. On the auto cycles the timer motor only gets voltage when the cycling thermostat opens. Voltage to the timer motor through a 4500Ω resistor when the timer contacts are open between T and X.

Wiring diagram attached. I do have continuity between T and X on the timer. If I'm reading the wiring diagram correctly, it looks like I may have inlet and outlet thermistors. Not exactly sure where they're located though.

I do have continuity between T and X on the timer.

OK, that might be the problem. Make sure you have the timer set on an auto cycle. In the off position it will have continuity. On the circuit board, measure the voltage across A-F and F-D

Ah sorry - I did have the timer in the off position I believe. Trying again and checking circuit board...

Confirmed no continuity with timer in the auto position.

This is where my limited knowledge ends. To check voltage on the board, I'm unsure if the timer just needs to be in an on position, or if the dryer needs to be running. Also if I'm measuring voltage across A-F for example, I assume I place a one lead on a leg of a component in the A path, and the other on a leg of a component in the F path? Amateur here....

Remove the board from the holder so you can maneuver it around. Leave the connector connected. Turn the board over and there should be enough metal trace in front of the connector to take voltage measurements:

With the dryer on and running I'm getting 120V from A-F, and 0V from F-D

Replace that board. The link is in post 4.

Thanks very much for all your help. Will report back with results.

Sound good. Keep us posted.

Control board did the trick. Thanks again for all the help - much appreciated.

Anytime my friend!
