Nordyne model MMHA-056ABHR-01, issue I am having is combustion fan kicks on for 30 seconds like it is suppose to before flame lights. As soon as flame is lite furnace will shut down for 5 seconds then restart and works perfectly. Doesn't do it all the time people have told me about pressure switch off combustion fan but mine is not equipped with that.
