Laars Minitherm trouble

Groz Member Posts: 1
My Laars Minitherm takes several attempts before it lights. I have to turn the power switch off and on about 5 times and the it lights. It only does this if it sets idle for a couple of days.

    Could Be.....

    Just a dirty flame sense probe down by the pilot. Or, depending on the age and state of tune of your Mini, the heat exchanger could be plugging up. If it's over ten years old and never been cleaned, get an expert to come out and give it a look.
