We have a Trane furnace xe 80 which stopped working now. It it the thermal protection device which needs to be replace. Where I can buy this part, and how much it generally cost? Very much appreciate your advice.

Ayuh,.... Is it the type that cuts the power, or the fuel,..??

Donno if the big box stores carry 'em, or not,...

If it's the electrical cut-off, 'bout any commercial Hvac supplier, or Electrical supplier oughta have 'em, in stock,...

If the fuel shut-off, the Hvac supply house would be the place to look...

How do you know it's not working?
Is it a main limit or a roll out switch?
An HVAC supply house that carrys Trane might be a starting point.

Could you post a picture of it? There are several types of thermal cutouts on the market. Some are even resettable

Find out what cause it to go bad. thermal limits on a furnace are safeties, not operating limits. So there is a problem that caused it to go out.

The heating system stopped working. Then checked and the diagnosis box shows "thermal protection device needs to be replaced".

The cause of its failure needs to be found and corrected.
