Electric Ignition Won't Start
I have a Lennox electric ignition furnace. When I turn up the thermostat I hear the furnace start (it even starts gas flow) but nothing lights.
It has a box where all the wires are attached to.
Here are the markings:
Robert Shaw Controls Company
Model No SP735L-- Lennox P/N 18G9101
Is there a blown fuse inside this box?
Does this problem have anything to do with the box?
Thanks for the help.
Re: Electric Ignition Won't Start
Don’t know but can tell you this:
In my last house the igniter burned out four times and in my present home it has burned out once.
My present furnace has a flashing light diagnostic code that helped figure it out but, I figured that’s what the problem was.
Now I keep a spare on hand and it’s a few minute change out.
