I have a Plus 80 and the gas furnace keeps shuting off. The error code is #14 "Ignition lockout" and then it refers to code 34 "ignition providing failure" So about every 3 hours it shuts down and I have to shut the power off for a few minutes and then turn it on and then it works. I have changed the filter thinking that would help (not). In the mornings when I get up the house is 63 degrees "cold" Any Ideas?
