Re: Lennox

Sorry, I wished I could be more percise on my answer, but your statement on the problem is too vague. An AC volt meter is necessary to check the unit. First one needs to check the cord to assure there is 110-120 volts AC present. If so, comtinue to check if the fuse is bad. If the fuse is good, it would likely be a heat senative thermal fuse. I hope this somewhat helps.

We have a Lennox furnas. It runs on propane. Sometimes it will not come on. If we turn off the switch by the fuse before the furnas, it will usually come on. This is not 100%. I have installed a new...

The unit is locking out on a safety. Do you have the model number of the heater? How old is it? This may not be a minor problem. You may want to call a Lennox dealer to assist you.

Lennox lf24 garage heater, starts then shuts down.

Here is a link to the manual for your unit heater:

The 4 flashes is a high limit or roll out switch is open. There are 2 or 3 little brown or black button looking switches with a little button on the top and a wire attached to each side. Press the button on each, you may hear a slight "click". If you do, that is the one that was open. Hope this helps.

Furnace will not heat.

Most of the Lennox G-16s that I have repaired were having problems with the gray Penn-Johnson Piggyback igniton control module.
This is best repaired by replacing the spark module. Sometimes it may be neccesary to replace the gas valve also. Lennox updated to a ROBERTSHAW ignition system. Honeywell can also be used.
Also check that there is no water in the pressure switch or tube.
Hope this helps.
