Hi I am Gaztech1, a independent technician, I will assist you with your issue.

Don't forget to rate the 5 star rating AT THE TOP OF PAGE if we are done. this will credit me for assisting you.

You need to take t-stat cover off and measure voltage ( 24vac ) between terminal R and C

If you dont have power, check small 3 or 5 amp fuse on furnace control board.

Do you have a volt meter or can get someone who has one and knows how to use one?

No, I don’t have a meter. I guess I’ll have to call a repairman
