Customer Question
My Lennoc Conservator III...

My Lennoc Conservator III G16 will not work

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

2 days now

Contractor's Assistant: Do you plan on doing the work yourself?

Yes I believe it is the ignition module

Contractor's Assistant: Anything else we should know to help you best?

The furnace is not doing anything when heat is called for

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

I changed the Batteries in the Thermostat, and I changed the filter

Model number SP735L, it does not have any LED lights, I think this is a real old one. It has been here since I've lived here, and I've been here 22 years now

Then you have a low voltage issue to the controller, check the low voltage transformer.
