Re: Indesit tumble dryer
The thermostats under the rear cover above the heating element are far more likely to fail, you should get simple continuity on both stats.
They come as a kit.
THIS is what you may need.
Handle the new ones with care, do not press on the bases of the stats.
Failure is usually caused by lack of regular cleaning of the filter and especially the condensor, opening the door to check on the dryness in mid cycle or sometimes motor capacitor failure.
