Frigidaire FG6T Furnace Reviews

"Flame sensor"

1.0 rating
Very Unsatisfied

I had a Frigidaire furnace installed by Economy Heating and Duct Works in 2010. When it was installed, the contractor told me to clean the flame sensor every September. Well, since then my circuit board, flame sensor and pressure valve have all needed replacing. I have to clean the flame sensor every 2 weeks or my heat doesn’t come on, but the service guy at Royal Furnace says it’s running normal. If you’re planning on a furnace replacement do not, under any circumstances, buy a Frigidaire.

"Owner of this pice of junk"

1.0 rating
Very Unsatisfied

We had the Frigidaire furnace( high efficiency) 2 stage and central A/C & heat pump installed in 06 model fg6tc o8o-vb. This unit has been bad from the day I bought it. Has service every year, won’t burn but 1 minute and shuts off, will not keep freon in it for 3 months and leaks out or something. 10 years parts and labor does not pay for freon or labor. The warranty stinks. Do not buy a Frigidare furnace. Good luck to the rest that have no problems with their furnace. This furnace and heat pump is a piece of junk. Thinking of pulling it out and replacing it with something else. Thanks!
