This one is driving me crazy. Customer finally wanted me to take a look. It would fire for a couple minutes then stop, would try again, igniter glow's and nothing.
Unhooked vent from wall and cycled well and ran well. Found a huge clump of lint at the outside vent. customer cleaned out and all was well for awhile. Then same problem.
Brought my lint eater and cleaned the entire vent system and got a decent amount out. Ran unit and still same problem.
All component's check within spec's so thought maybe the coils were going bad and not opening when hot. Replaced gas valve no luck, same issue.
No vent blockage, new gas valve no change, all components check out and within spec.
Ran a diagnostic per dlg2524 manual and the first number's flash between18:98 and 1U:01; second moisture 255 (specs 70-239); drum temp between 30-31 (not sure if this is in celsius) drum was actually at room temp.
The first number's don't make any sense to me for a fault...am I looking at a bad control board or possibly weak high limit thermastats?
I jumpered the resetable therm. and no difference, could it be the automatic reset high limit on the blower?
So lost, could really use some help...must be something simple I'm missing...help!
Gonna try and run a video of the diagnostic I did.
