Nordyne M1MB070ABW - No Heat, Blower On

Hello ... I live in a very rural area and it's hard to get service for my furnace, so I need advice.

When the furnace kicks on, the red light is on steady, but the yellow light flashes on and off, once at a time. The sticker on the furnace says "yellow light flashing = low flame." The blower is on but there is no heat.

Nordyne M1MB070ABW model number. Double-wide trailer.

I can order a part and have it installed, but I'm not sure what part to order. Advice on how to determine what is wrong and what is needed to fix the problem is desparately needed! Thanks :D

Hi,

Check your burner tube and the main burner orifice for a blockage such as a spider/spider web.


Your furnace either has no burner flame or a low burner flame.


IF the burner and orifice are clear and not clogged, you'll need a hvac tech to test furnace for correct gas pressure and gas valve operation.


Take care and best wishes,
Robert
