Evening all,
I woke up this morning to a cold shower since my HW Heater stopped working. I did all the basic verifications, 12V was good, Gas was flowing ( stove and Heater were working fine ) I could hear the DSI Firing but no ignition. I went about my day and this afternoon pulled out the multi-meter and started to check... First thing was to see if I had 12v on the sol when DSI was firing. No 12v. perplexI looked at the wiring diagrams again... determined that if I had DSI working and sparking then I had power to the control board and this was not an issue with a bad thermostat or over-temp sensor. I decided that I would call Heartland and walk through what I had done to see if I missed something. Customer service and I reviewed the situation and decided that this was something that Suburban needed to help with. I then called Tech support at Suburban and did the same walk through with them... he had me remove the leads from the two LP solenoids and check the resistance of the coils to see if they were shorted. one read fine at 42-44 ohms but the second read 4 ohms it was a near dead short. The next thing I was told to do was test to see if the board was still providing 12v when DSI Fired with the leads still disconnected I caused the unit to attempt to fire - and I got no power on the brown wire at all.
Conclusion is:
1 Dead solenoid, ( need to replace the entire valve assembly )
1 Fried control module.
Now in my cyclone 3010 how does one get to the DC control module?

or better yet, I'll take it to a service center and let them fight it ... Some battles are just not worth fighting I think.
