atwood heater 7916-II problem

[gregb]

Please help.

I have an 08 Jayco under warrantee. Dealer cant get me in.

Here's the problem. Turn on heater. Fan Blows. Tries to light. 3 times them led flashes 3 times pause 3 times pause...on and on. Reset heater and thermostat.

Here's what I have checked. Battery fully charged. Camper on Shore power. Full tank of Propane. Propane at gas valve on furnace. 12+ volts at each solenoid on gas valve when trying to fire.

Note looked at circuit board when firing and little resistor/capacitor flashing when trying to start. This resistor/capacitor is next to the large blue object on circuit board.

This Camper is under 2year warantee so I have to be careful. Don't want to void the warantee.

All help is appreciated.

It sounds as everthing is a go and either there is no gas or the spark ain't correct!
Knowing that it attempts to light indicates it passed all the other steps! Themostat, relay, circuit breaker, blower motor, sail switch, limit switch, ...

Ask the dealer or Atwood if there is an authorized service center other than the dealer.

Just to update everyone.....I spoke with Atwood and was to to check the pressure regulator. Set to the proper setting and now the furnace and hot water tank function great. Too bad the dealer wouldn't tell me this.
