Hello... I have a Nordyne/Intertherm MMHB-070ABHR-06 furnace with a United Technologies 1018-204 controller. It does not ignite. The controller clicks once about 30 seconds after I power it on and then repeatedly flashes the diagnostic light two times. I do not have a manual and I don't know what the two flashes indicate on the controller. I have replaced the ignitor but it's still doing the same thing. I replaced the ignitor because it's the most common part to need replacing. The furnace was working fine last winter. Does anyone know what the two flashes on the diagnostic light is indicating? Any advice will be appreciated. Thanks!
