Kenmore Dryer No Heat

[stu22180]

Hello,
My Kenmore Dryer Model 110.82824102 no heat. I have tested the below items.
Heater coil "Good"
Thermal cut-off "Good"
High limit thermostat "Good"
Thermal Fuse "Good"

I trace the problem back to the Control Board heater relay. The relay dose not turn on when the Dryer is running. Is there other testing to Control Board I can do?
Thanks Stu

Check the thermistor. Copied from the tech sheet:

1. Unplug dryer or disconnect power.
2. Remove the toe panel to access the thermal components. See figure 15, page 10.
3. Using an ohmmeter and referring to the
wiring diagram, measure the resistance
from the red wire at the thermal cutoff to
the red wire at the heater.
➔ If the resistance is about 10 ohms, go
to step 5.
➔ If an open circuit is detected, go to
step 4.
4. Visually check the wire connections to the
thermal cutoff, high limit thermostat, and
heater. If connections look good, check for
continuity across each of these
components. Replace the one that is
electrically open.
5. If no open circuit is detected, measure the
resistance between P2-5 (red/white wire)
and P2-6 (black wire) at the machine
control board.
➔ If 6–7 k ohms are measured, replace
the machine control electronics.
➔ If the resistance is less than 1 k ohm,
replace the thermistor.

This is a note "What fixed the problem"
I got a new controller board PN:8557308 and pluged it in. Now the Dryer works.
Thanks for all your help.

I've had a couple of those dryers with bad boards. If everything checks out and has continuity, I replace it or part the machine out.
