My minimax heater doesn't ignite. Air blower fan keeps blowing forever and service light is on. I take off rubber tubing and blow some air directly into air switch, then I put tubing back and it works for day or two. Here is the picture of the switch. What does .65"VF means? I couldn't find exact part number, but found RSS-495-11 model from Grainger.
Anyone knows if this would work? Thank you
