Duet Dryer GEW9250PL0 temp controls not changing temp

[Dan O.]

The dryer code of E1 comes on after about 1 minute and flashes

If the sensor tests good and the wiring isn't an issue, i can't think of anything else than the electronic control.

You could make sure the dryer is venting properly. Maybe its an airflow problem? Try running a load with the venting totally removed from the dryer to see if the functioning changes?

I don't have anything else to suggest.

Question on wiring on Thermal relay connected to circuit Board. If I switched the black and red wire on the relay would this cause the issue. Can you tell where the black and red wires go or does it matter? Videos show conflicting locations.

Just tried dryer without the venting connected, No difference, still E1 error code. Let me know about question above. Thanks

I don't know what you mean by a thermal relay. If you tell me what terminal numbers each wire is connected to, I'll try to find out if they're correct or if their position would make a difference.

I mean the black heater relay on the control circuit board. Attached 2 pictures showing different connections. 0731 is upside down.

 

[Dan O.]

If there are only 2 wires, it doesn't matter which wire goes where. The relay effectively just connects those wires to each other when activated.

Installed new control board and thought it was the answer since dryer didn't cut off after 1 minute. Kept dryer on and changed the temp settings to make sure the heating element was OK on all settings. After about 4 minutes the dryer stopped and showed E1. I unplugged the power and waited until Thermistor cooled down and it checked OK. I restarted and error code came on after 1 minute. I'm frustrated. Any other suggestions. Thanks

 

[Dan O.]

The only other thing I can suggest is to trace the wiring all the way from the control right to the thermostat. Maybe at some point it shorts to ground causing erroneous readings?

There isn't suppose to be any other causes for that error message.

How to do I test for a short and where should I test. I'm a DIY senior citizen trying to avoid a service call if possible.

If shorted do I replace the entire wire harness.

 

[Dan O.]

I suggest trying a physical inspection of the wires looking for any signs of rubbing, melting or for it being pinched. If the short only occurs after heating it may not be measurable when cold.

If you want to try to measure it, disconnect the unit from power, put a meter on the highest ohm scale, disconnect the harness at one end and test from each wire terminal to a ground surface. There should never be any resistance measured.

PS. If testing don't touch both meter probe tips with your fingers. The meter will detect the resistance of your skin.

If shorted do I replace the entire wire harness.

No, just reinsulate the short or splice as appropriate.

just to be clear when you say thermostat are you meaning the thermistor or hi-temp thermostat on heating element?

 

[Dan O.]

when you say thermostat are you meaning the thermistor

Yes the thermister. Sorry, I misspoke.


Dan O.

 

[jimgil23]

I see no issues in the wiring. Resistance still checks OK at both ends. Hard to believe that I will need to buy a new dryer. Went to local appliance repair company and told them my situation. They keep saying Thermistor but I replaced this again. They would come out and diagnose but said they would do everything I have already tried. Not sure if a different set of eyes makes sense. I'll keep trying if you have any other suggestions.

 

[Dan O.]

Yes, I'm sorry that's a head-scratcher. I don't know what else to recommend.

Just tried dryer without the venting connected, No difference, still E1 error code.

Besides bad external venting, there might still be a problem with the internal air flow. Look at this previous forum message:

FIXED - GGW9200LW1 Whirlpool duet Dryer - Error Code E1

I replaced drum felt. Afterwards I got an E1 code which told me replace Thermistor. Dryer starts but still shut off with E1 code after a few minutes. Running with vent completely unobstructed. Circuit boards look fine. What else could be the problem??? HELP!

I had taken off blower housing and vacuumed for lint but did't go further into dryer. I have cleared all lint from the exhaust piping so it is completely lint free. What about using a dry vac blower at the blower housing to see if any obstructions are removed. Otherwise I guess removing door is the only way unless from vent in back of dryer.

I'm sure an obstruction isn't limited to just the blower housing but doing so might not hurt. It still might require further investigation though.

Couldn't find any obstruction at blower housing. Removed cover and used vac to blow out some lint. After putting back the blower housing and attaching the wires to the thermal fuse and thermistor, there is now no heat to the element. I tested every component and they seem OK and no short to element housing. I did notice that the E1 code came on when I set the controls to heat eventhough there was no heat from Element. I think the dryer is possessed. What about the control buttons on the front panel. Any issues with these to check out?

Maybe a wire came off? Did you confirm the full 240 volts is still getting to the dryer?

the E1 code came on when I set the controls to heat eventhough there was no heat

I was thinking, maybe it is a hold over fault code from a previous issue? Maybe try putting it through a diagnostic mode and then cancel it. Maybe it will clear any previous fault codes?

I'm afraid I have no other ideas than looking at everything involved in the venting. Make sure the fan is on tight, all drum seals are in good condition, the lint filter is not clogged. Check if water will pass through the lint filter. Dryer sheets residue can clog the lint filer screen and also hamper air movement.

Good luck!
