Actually better for constant fan than cycling on the motor! Yes, it could add $20-30 to the monthly juice bill. A tech would know right where to look for the problem. Probably should have an authorized Lennox dealer to a pressure test on that relic to be sure the heat exchanger is safe.0

I remember having trouble keeping them running in the early 80's.1

I don't do air, but if they are anything like pulse boilers, if the gas doesn't shut off, it won't shut off. Just like a diesel engine. They operate on latent heat ignition.0

Is it only the fan that keeps running?0

After 6 days, the OP either solved the problem elsewhere or he "cooked" his whole house with runaway heat.0

Glad you have an accurate pulse on this one.0
