DSI Fault

[rockcandymounta]

While trying to figure out what is wrong with my furnace not wanting to come on. I noticed a red light in the DSI panel that says DSI fault. Would that make it so that the furnace or hot water would not come on? If there is a fault how can it be corrected?

Does the stove top work? All burners on and blue?
If no burners, no propane. Tank valves off?
MH or trailer? Some MHs have solenoid to shut off propane that operates off carbon monoxide detectors.
Bad regulator

So, I watched a video on DSI faults. Learned a lot. However I still think that it has to do with gas supply. Which confuses me because the burners on the stove come on. I ran them for several minutes.

Throughout the morning, I have tried to start the furnace and first the blower comes on, then I hear what sounds to me like the flame working, but after 15-30 seconds it shuts down but the blower runs for a bit longer.

Often times, if propane is not readily flowing, the fault light will come on, after making several attempts to light. You can turn the switch off for a bit (maybe a minute or so), and retry to light. It can help to get air from lines by lighting stove burner for a bit, if air in lines is the problem.

After reading some other posts regarding DSI, I see that it is Direct Spark Ignition. It lights up after 3 attempts at lighting. I turned on the stove burners and I have gas there. I switched to a new tank that I know is full.

Both the furnace and the hot water tank now do not want to light. Sigh
