Evcon furance code 5
Posted: Mon Nov 26, 2007 8:39 am
I have an Evcon furnace model DGAT075BDD and after the local propane company came over and installed a new tank and checked the furnace it began to not run right. I’ve replaced a few parts but its still acting up and giving me a code 5 now. But here is a list of problems and fixes I’ve done to try to repair the problem. I see that there is a code 5, but what is my next step?
Problems in order:
1. Furnace igniter would not energize
a. Fixed by jumping the high limit switch, then replacement
2. Furnace kicks on now but would turn back on when it should not turn. For example furnace would turn on when temp was SET at 65 and the inside temp was 75. But only the blower would turn on.
a. I replaced the thermostat and the circuit board.
3. Now I am getting a code 5. (gas valve energizes without a call for heat)
a. So the furnace will turn on heat and then cycle off normally. Then the second time it gives the code 5 and only turns on the fan.
Any tips would be helpful.
Thanks
