suburban furnace

[Ghislain]

Hello
I have a problem with my suburban furnace SF35F when the blower start running and the heat came out, they only run for maybe 3 to 5 min. and the blower and all the light go up and down like a disco. I like to know if somebody have the same problem before and what could be the problem.

Thank You

Check your battery voltage while you are running your heater with a multimeter. Sounds like a low voltage discharged battery issue.
