What are common Goodman furnace problems?

What are common Goodman furnace problems for models like GMSS92 single stage 92 percent AFUE, GMVC96 two-stage variable speed 96 percent AFUE, and GMVM97 modulating 98 percent AFUE include igniter failure, flame sensor dirty, and pressure switch issues similar to other brands but with Goodman-specific frequency. First, hot surface igniter failure after 5 to 8 years causing furnace not lighting, igniter is silicon carbide element that glows orange to light gas, cracks due to thermal stress, showing error code with 1 flash on control board LED, replace igniter at 100 to 200 dollars installed, common to all brands. Second, flame sensor dirty causing furnace to light then shut off after 5 seconds, showing error with 2 flashes, flame sensor is metal rod in burner flame that detects flame, gets coated with carbon, fix by cleaning with fine sandpaper. Third, pressure switch failure showing 3 flashes due to blocked vent pipe with bird nest or ice, clogged condensate drain for high efficiency 90 percent plus furnaces causing water backup, or failed draft inducer motor at 300 to 600 dollars. Fourth, dirty air filter causing high limit switch to trip and shut off furnace due to overheating, replace filter every 2 to 3 months. Fifth, blower motor failure after 12 to 15 years at 400 to 700 dollars. Sixth, control board failure after 12 to 15 years at 300 to 600 dollars. Goodman specific issue with thin gauge heat exchangers that can develop cracks slightly earlier if not maintained. Service rates around 10 to 13 percent indicate decent reliability for price. Regular maintenance prevents most common problems.
