Coleman EvCon mobile home gas funace ignition problems
I have a Coleman Evcon DGRT056AUA gas furnace.
It is in a hunt camp and is not used very often, so I tend to have
issues every year getting it working.
Usually it will eventually fire and work, not so far this year.
I think that it is likely the re-igniter module. Typically slide gas valve lever to pilot and depress, The igniter can be heard ticking (sparking) continuously as it attempts to light pilot. Usually alot of air in the line so it can be a process. This year I can get no sparking of the igniter.
Switch on igniter is on, 24v is measured going to the re-igniter module, but nothing out. It has a high voltage wire (similiar to sparkplug wire) going from module to burner assembly, to spark unit. I even have voltage at the transistor in the igniter module.
My problem is unit is 10-15 years old, new mobile home unit appears to run around $800-900. The re-igniter module appears to be about obsolete and is quoted as about $115-160
this Coleman part number shows #7970-378P/B
my part on the actual unit (it may have been replaced in the past)
Watsco 7000AAF526, again this module is pricey.
However, I see a module ROBERTSHAW 785-001 that is a
pilot re-igniter, comes with the electronic module, spark wire, spark unit etc. all for about $40. This unit also works off 24v, what would be the
issue of getting this unit instead of the $150 module?
I mean a spark is a spark, they are both re-igniters, designed to re-fire a pilot light if it temporarily goes out.
Any opinions about this from you guys.
I am hoping to get another year out of this older unit before biting the bullet for a new furnace.
Thanks in advance for your help.
