Does it try to start or lite. Russ
Does anything work. Russ
Strange for two furnaces acting the same. Do you smell propane when the unit tries to light. Sequence of operation should be the small fan comes on for 10 seconds, igniter glows for 10 seconds,gas valve opens and unit fires. What flash code from the LED do you get when it tries to fire. Russ
That is 14 ignition lockout, The problem is with valve or regulator. Crack line before valve and see if you have pressure. Russ
Yes. The regulator is on tank. We need to know if we are getting gas to valve. Anywhere close to valve if you just crack line to see if you have propane. If gas valve was opening you would smell propane if it did not light. Russ
Anywhere close to gas valve. Any other gas appliances in house.
Usually there is a flare or a union in line that you can unscrew to check to see if you have gas. Russ
