Goodman heating unit problems
Asked Nov 29, 2006, 02:11 PM
Hello, I have a Goodman :( heating unit in the house that I moved into model GPM100-4.
When the exhaust fan comes on to clear out the system before the unit will fire up. It makes a clicking sound. I have learned that it’s trying to pull a vacuum from the exhaust fan to a safety switch. If I suck on the vacuum hose it will make the switch and the clicking stops unit runs fine. If I don't, it may click fifty times or click until it times out. I have replaced the pressure switch, hose and fan, but still has not changed anything. Just wonder if anybody else has seen this?
