Housekeepers here yesterday, dryer got a workout. On last load of towels, the dryer kept blinking out and running cold.
Open door, restart and it lights, after a while goes cold again.
I replaced the igniter a couple of years ago. Glowing nice red hot drawing about 4.2 amps.
Solenoid with 2 terms (marked 4, 5 on most diagrams) showing 1232 ohms with a spec of 1220 +/-50
Solenoid with 3 terms showing
1-2 @1355 ohms with a spec of 1365+/-25
1-3 at 560 ohms with a spec of 560 +/-25
Very short alum. flex duct all clear; no lint, and duct clear inside dryer.
Perhaps the flame sensor?
If it starts acting up again I'll sit with it and see if I can hear the solenoids kick in when it gets cold.
I am otherwise at a loss.
