Loud buzzing sound on XV95 Trane furnace - Goodman Heating & Cooling

replace it

That sound generally comes from a magnetic coil that is being energized. It could be from a compressor control or a furnace gas valve. In either case there is no danger involved it may buzz for years and unless you have money put aside for a heating mans adventure id just let it buzz until it gets so loud it just has to go. Sometimes the buzz just goes away. I know it sounds crazy and I understand one persons buzz is another persons nightmare. Its yer call. Hope this helped and good luck.

worth checking over heat temp sensors (klixon ) sensors can cause heater to go into a cool down purge Through an open circuit heat exchanger (Klixon ) temp sensor Ive seen before good luck

There is either a problem with the ignitor or the flame sensor.

goodman makes a very good furnace and just as durable as a trane at a fraction of the cost. i'll stand behind goodman just as i would a trane.

Sounds like a bad motor winding.

dodgy relay possibly

Could be correct, or you may have something in your fan that either fell into or crawled into your fan through the exahust duct.Since you have a service contract, have they actually been out to look at it or did they tell you that on the phone. It might be worth removing the fan and clear any forign matter. The problem is the labor to do that would be the same as to replace it. What does your service contract cover??

if it is a mechanical thermostat the heat ant. does that on cheaper digital tstats it is set by span and on better stats like honeywell model 5000,6000,8000 series you set the cycle rate. what kind and model number is tstat

How about the Heating/cooling thermostat. Sounds like you better check it.
