My heater was working fine this past winter. And I even turned it on in October once and it was working fine. I live in a mobile home and have an Intertherm heater. It keeps telling me the pressure switch is open and won't turn on. I don't even know what the pressure switch is! It does the normal "humming" sound when first turned on. Just heater or blower never comes on after that. Any help would be greatly appreciated! Thanks in advance. A/C works fine. Not sure if that matters.
