Furnace cycling

Gary Stone · 2005-03-12T16:25:04+00:00

Hi, I've got a forced air propane furnace, Luxaire model GSU082MF Series NAGOE (could be a Q) serial #1310002Controlled by a Honeywell T87F heat only thermostat. This morning I was down in the basement and noticed that it had the initial ignition then that cut off after a while (normal burn) then a couple of minutes later a second ignition which ran a couple of minutes, when that cut off I headed up the stairs only to hear it kick in a third time for a couple of minutes. Total time for this was about 10 to 13 minutes. Before I went down there I had moved the thermostat only to the point which it kicked in, 60º F from 58º F so, it wasn't that drastic a jump. Yeah, I like it on the cool side. The outside temp was 19º F. I do not remember it ever acting in this manner and suspect there might be a problem, Yes? No? Thanks for any input.Stone

Judging by his description this will not fix the problem.
