Heat pump/air conditioner is cooling, but 10 killowatt coils (aux. heat) come on with A/C. Can I temprarily disconnect Heating coil wires? I own an American Standard TWE030C140A1 furnace hooked up for 2 stage heat, single speed cooling and a Heratige 10 A/C / Heat pump. 6H 00.0A100A3.
Answers: Yup, it's a service hail as. Could be a bad stat, shorted control electrics, hung relay, bad sequencer, or a impossible board.
your heat/a/c valve is sticking or out of order. most problems like this are electrical. you may hold a timer relay that needs to be address. call the businessman and they will a tech that may help you over the phone.
