Intertherm blower shutting off

[Bobby rose]

I have an Intertherm propane furnace in a moblie home, the problem I am having seems to be intermittent, furnace will start and takes about 1 minute before blower comes on, then it runs for about 30 seconds a cuts back out, satys off for about 30 seconds and then runs fine. Blower model number is 911030. Not sure where the model number of the furnace is. Also, after the thermostat temp is reached, unit cuts off, but a few cycles of the blower coming on and off run. Any information would be greatly appreciated. Thanks in advance!

Model n umber will be on furnace facing data sticker or nameplate.


Thanks,
