Just a generic question for all other techs here:
You have a gas dryer with a "Not heating" complaint.
You show up and start dryer check temps and it is heating fine, running for 5 to 10 minutes checking cycling temps in hi and low settings all are OK.
What do you do:
1) keep waiting and watching to see if ignitor glows and burner doesn't light to know and prove you have bad gas valve coils.
A) How long do you wait to prove this?
2) Just assume you have bad gas valve coils without proving it and go about cleaning/checking rest of unit and replacing coils.
The reason I ask is I had another one today that took 16 minutes before the coils actually broke down and failed so that I had proof this was the problem, (I really detest replacing something if I don't have definite proof it is bad).
In the past I had one that I had let cycle on/off for about 1/2 hour and it never missed a beat so I assumed it was OK and just had bad users/tenants. Got a call back next day said still not working, went out and checked again - this time coils broke down and failed in 5 to 10 minutes.
So basically how long do you let it cycle before giving up and saying all is OK or do you just normally assume must be a gas valve coil problem and replace them?
Thanks for any feedback on this..................
