SaferProducts.gov consumer incident report 20220326-BA660-2147357113. Severity: Incident, No Injury. Product: Carrier 58CTX090-16 (Carrier Home Furnace, Model 58CTX090-16, Serial number 1912A18166, Series 140, Mfg May 2012, light greenish in color). Incident: Furnace made a poof sound. Thermostat display was blank. In a few minutes, went to garage to check. Furnace was off, but there was a burning smell and furnace panel was hot. Took off furnace panel and stickers inside were burning/melting. All 4 burners had flames about 3 inches tall. Turned off power to it -- burners still stayed lit! Had to turn off gas. Called a service place. They came out and determined the gas valve had stuck OPEN! The resulting heat also melted some transformer wires. Cost us $1000 to repair. If I hadn't happened to be home at the time, we could have easily had a fire or a gas explosion. Furnace is a Carrier, Model 58CTX090-16, Serial number 1912A18166, Series 140, Mfg May 2012. I have the defective gas valve and would like to send it to Carrier, but they're such a big company I don't know how to get it to them.
