hYDRO fLAME fURNACE

[Don Barber]

Hi,
My In laws have an older HydroFlame furnance that occasionly will not fire. Motor runs but no heat. Will do it either on 110 volt or on 12 volt. I have checked both 110 voltage or the 12 volt and even when it doesn't fire voltage is up to 12.65 volts at the control board. Any suggestions? Control board, sail switch? Can I vacumn the burn chamber? Looking for ideas before we head back north in a few weeks.
Thanks Don

I don't see why you couldn't vacuum to tube. I had a control board problem my water heater. Sounds familiar.

Hi Don,

I have a 1995 Hydro-Flame furnace... And I had the same problem...

The most common cause is dirt-dauber nests on the burner assembly.. which does allow the gas to be ignited by the spark.

It's easy, although a little aggravating, to remove the entire assembly and clean...

#1. Turn off propane at tank
#2. unplug the wiring harness from the mother board
#3. disconnect the gas line fitting located next to the furnace
#4. remove the one wing nut located on the upper edge just inside the door
#5. slide out the entire unit... it may take some "wiggling" to get it out
#6. Clean off the clay "Globs" and blow out everything with an air hose or brush everything good with a brush of some type.

#7. Reassemble everything in reverse of how you took it out..

#8. Use a soapy water mixture to check for leaks at the propane line fitting after you screw it back together.

#9. turn on propane at tank and turn up thermostat for a test run..

This entire procedure should take about 30 minutes or less... and you can do it yourself...

thus saving a bunch of money paying a repairman to do it..

If after cleaning the unit, it still does not work,, then, you can call the repairman.

Around here they charge $85 per hour plus a $25 "Road Fee" to come out..
