I live in a mobile home and have the furnace model number MMHA-090AA.
Last year it worked fine. This year i can't get it to ignite. What happens is that it sounds like it wants to run and then it shuts off and a red light blinks. it flashes once then in succession of 2 blinks...then stops then 2 blinks. I am not sure what is going on but before I call a repairman, I would like some insight on it.

2 blinks is a flash code. Should be a data sheet attached someplace on the furnace near the control box that states the flash code status. Could also be on the backside of the electronics cover panel for the furnace. Locate that and it will help you diagnose your problem.
