The dryer will not start. I checked continuity on door switch, thermal switch, but the push-on switch is questionable. What is the correct way to test it? If that is not the problem either, what next?

My gas dryer won't start (LGT 7646DQ1) There is power and the inside light works. Continuity tests showed no problem with thermostat, sensors, door switch. How do you test the push start switch when apparently a relay inside the switch resets every time the door switch opens and closes, as well as when the timer cycles off and on? Do you have to test it when the relay is in the "on" state? or not? or, exactly how do you test it? I am about to test continuity in the timer switches according to the wiring diagram that was taped inside the cabinet. Which of those connections, if not working, could cause the dryer to not start? If the timer has any malfunction, there goes my next/last $100!

Here are the parts Replacement parts for WHIRLPOOL LGT7646DQ1 | AppliancePartsPros.comHere is the wiring diagram https://www.servicematters.com/d...0Sheet%20-%203401723.pdfContinuity tests showed no problem with thermostat, sensors, door switch. Did you remove at least on of the wires from any device you were measuring, just to ensure you were not reading an alternate/parallel circuit path?
How do you test the push start switch You only have to test the contacts when pushed on. If they are OK then your dryer should still start but would stop as soon as you release the push to start. I am about to test continuity in the timer switches according to the wiring diagram that was taped inside the cabinet. Which of those connections, if not working, could cause the dryer to not start? BK/BU contacts and Timer Switch 4 Motor's circuit path is Neutral , Door Switch , Timer Switch 4 , Centrifugal Switch , Motor Windings , Push To Start Relay contacts, timer contacts BU/BK , L1 |

Thank you Denman. Timer Switch 4 seems to be the culprit, showing 0.L at all positions of timer. I still wonder about the push-to-start button tho. Should it read 0.00 when pushed on or does it have a 1.8 load like I'm seeing?

If you are measuring from R1 to R2 (the contacts) they should go to zero when closed. Could be they are a little dirty or pitted.
Note it is always a good idea to short your meter leads together when reading resistance. This will tell you where meter zero is. Also keep them clean. |
