I have replaced a Honeywell thermostat with a Hunter Model 44155C Programmable thermostat. I feel that I have connected it correctly but it still will not come on. Some one told me to check the regulator. Could someone please give me some input?

What was the reason you changed the tstat?

Because the Honeywell went blank and would not turn on

OK, what kind of unit do you have? It cold be many things, sounds like you might have a bad transformer, has it stormed bad in your area lately?

Wouldn`t trade a dead honeywell for 10 hunters they are junk

I agree that's why I asked why he got rid of the old one

The gas furnace is a Lennox and yes, it has been raining quite a bit in Southern California
Question? I really don't know very much about furnaces, so where is my transformer?

Its inside your furnace, there is a control panel inside, you can see the tstat wires and the hv wires going in the side, take off that panel and its in there

What exactly am I looking for on the transformer?

A lot of time you will see wires burnt, smell like its burnt, check to see if that model has any fuses or reset switches inside the control panel

I opened it up and nothing looks, smells burnt. Everything looks good

It's a Lennox G12Q3E-82-4 gas furnace

Did you check your breakers and all, if the furnace does not have power the tstat will not work
