I don't know,Gary, but often when weather switches a heat pump over to backup heat we find operating defects in the backup system that were there for a long time but never evident because the backup wasn't in use. Also check for an open blower door or a condensate overflow pan that is full. He says that the pan unit needs to be replaced at cost of about $400. %%EOF
