Frigidaire FG7MQ Furnace Reviews

Showing 6-8 of 8 reviews


5.0 rating
Very Satisfied

I had my furnace “red tagged” because the heat exchanger was gone. I called another contractor to have it checked and there was nothing wrong with the furnace, it was just old and did not have to replace it. A year later I called the same contractor and because my furnace was 21 years old I had it replaced. The Frigidaire FG7MQ unit he put in saved me money on my gas bill and was very quiet. I do not have to turn up the tv when the furnace turns on. Thanks Luke.

One Frigidaire gas furnace owner writes on that his furnace will only operate properly with the cover removed. A contractor suggests removing the flame sensor and cleaning it with fine-grain sandpaper. This action solves the problem; several other readers report this has helped their furnaces function properly. One expert suggests that this cleaning should be done annually. ranks this Frigidaire furnace as having four out of five stars. The FG7MQ, with its iQ drive, is the top of the line of the Frigidaire gas furnaces, and the communicating thermostat is a real plus for establishing comfort in the home.

A homeowner poses the question on of whether there is an easier way to clean the heat sensor than scrubbing with sandpaper or steel wool. A contractor suggests carburetor cleaner, but the homeowner says even that solution has not worked. The problem with charring and oxidation on the flame sensor seems to be the main issue mentioned online with Frigidaire gas furnaces.
