My intertherm furnace model MMHB-070ABHR-06 won't light. The red light on the curcuit box is blinking twice.

Hi and Welcome,
I am not able to find a code light manual for your furnace. So i was wondering if you can look and see if anywhere on your furnace or furnace doors that there is a trouble code chart. If not then at what point does your furnace begin to fail. Here is a link on the basic operation of a furnace. This will be helpful in figuring out when your furnace fails to start.

Hope this helps

Was this issue resolved? I'm having the same problem with a Nordyne/Intertherm MMHB-070ABHR-06 furnace with a UTC 1018-204 controller. The controller clicks once after about 30 seconds and then repeatedly flashes the diagnostic light two times. I have replaced the ignitor but it's still doing the same thing. Any advice will be appreciated. Thanks!
