Whirlpool gas dryer high heat only

Dryer Repair
1

Dryer runs on high heat only.Timer advnces on timed setting, but not on auto settings. Low heat auto setting runs on high heat only, and does not advance the timer. Air fluff setting does not advance, and runs on high heat only. Dryer worked fine until thermal fuse blew. Replaced it, and since then the problem described started. Have replaced the high heat thermostate as well as the cyclic thermostate. Have gone completely through and cleaned everything, so no obstuctions. I don’t believe there is a dryness sensor on this model??

Very likely the problem is a bad coils on the gas valve.

Thanks for the fast reply. Guess I forgot to include the fact that I also changed both the coils already. Is it possible that the replacements might have been bad, or that they could have gone out?
Should I try changeing them again? Could it be the timer?
Thanks again.

Sorry for the delay.

Looks like the problem can be a bad timer.

Label all wires and remove them from the timer. Set the timer on auto-low heat and check for continuity across the terminals: TM-OR, BK-BU-V, BK-BU and BK-R. If there is no continuity in any pair, replace the timer.
