Would you please tell me where (or if there is one) the reset button on a Carrier Weathermaster 9200 would be located? My gas furnace has gone out again and I would like to do anything possible to fix it before calling in a furnace repair man. It is about 12 years old.

Turn the main power, 120 volt of to the unit for 15 seconds. At the switch at the furnace or at the breaker box

Also be for you do this if you take the bottom door off the furnace and look in the sight glass it should be flashing a code. It will tell you what is wrog with the unit
