Intertherm Model # MMHA075AAHR-01 with electronic ignition. Won't ignite. Diagnostic box is blinking twice. Does anyone know what that indicates? Blower motor works when turned on manually but blows only cold air. Seems like we had a similar issue last year and were able to have the limit switch (?) replaced. Desperate for answer, my Mom is without heat in a mobile home with single digit temps!
