This hi-limit thermostat acts as a safety mechanism that keeps the dryer from overheating. Once the dryer temperature reaches a certain point, this piece will shut down power to the heating element.
Removed top of dryer and front panel. Keeping the front door closed I was able to start the unit and observe if the gas was igniting to heat the unit. Found that no flame was present. Examined the ignitor (found the locatino after utilizine this website parts diagram) and noticed it was cracked. Ordered the new part and it arrived two days later. Simple installation and ta daaa....ignitor works, hot dryer again. *Only reason it took over half an hour was because I cleaned out all the internal vents while the unit was opened. Basic mechanical abilities required here but remember to unplug the unit while working on it!
First I unpluged the dryer, removed the two screws from the bottom access panel. I used a small socket to remove the screws securing the limit stat to the burner chamber, nut driver was too long. I installed the new limit stat with the two screws and attached the two leads. Plugged in the dryer and conducted a test run, burner ignited. I turned the dryer off and replaced the access panel.
