My gas furnace doesn't fire-up although I hear clicking inside every time I attempt to toggle the switch bypassing the thermostat. Is it SAFE to short the LIMIT SWITCH to check it that's the problem. Because I remember the furnace was left for several hours running and then all of a sudden it just stopped. We use to override the thermostat adjustment.

Thank you so much!


Sincerely
Dan

Hi, Dan!

Greetings and WELCOME to the site! I just moved your question that you had posted in Introductions to this forum topic area so that it would get the most exposure to those who are best able to answer it. Introductions is for people to introduce themselves and we try to not ask questions there.

It can be a little confusing when first learning how to use this site! Your question will get noticed much more in this forum topic area.

We would appreciate it if you would return to Introductions sometime to tell us a little about yourself though, if you would be willing to do that.

Thanks!
