I have a 2yr old heating system from Payne model # PH15NB02400G. One day we noticed the Drain pan under the unit, in the basement was full of water. Then it stopped working! It has a Float Switch Model AquaGuard AG-1200+. Somehow we have lost all manuals and troubleshooting guides. Is there a reset button on this device, I could do myself?? We are looking at possible foreclosure and way behind on bills! Can you please help? Maybe a website that you can recommend to replacement Manuals and guides?? We are having to spend any money we can come up with to buy firewood that heats maybe 2 rooms!! Please help!!
