Suburban furnace - no spark issue
I have a 2010 Gulfstream TT. I tried searching the forums but majority of the issues I found were for no ignite problems. My issue, I have no spark at all. The fan turns on under normal operation...

Thanks for the tips. I should add, we went camping last labor day and the furnace worked fine the first night, then stopped the second. My stove has good propane flow and so does my hot water heater which is further down the gas line than the furnace.
I'll check the limit switch tonight. Can the sail switch be cleaned without removing the unit?
If the fan is running like it should then the sail switch is OK and does not need cleaning.
The only way a bad sail switch will keep the fan from running is if it is stuck closed. The fan will run fine with a sail switch failed open.
