What are common Goodman problems?

What are common Goodman problems for AC, heat pumps, and furnaces include capacitor failure, igniter failure, and coil leaks similar to other brands but with some Goodman-specific frequency. For Goodman AC and heat pump units like GSX14 and GSZ14, common problems include capacitor failure after 5 years causing outdoor unit not starting and humming, costing 150 to 300 dollars installed, common to all brands but slightly more frequent in Goodman. Contactor failure after 7 years causing unit not turning on, costing 150 to 250 dollars. Refrigerant leak from evaporator coil due to formicary corrosion after 5 to 8 years causing low charge and ice buildup, costing 600 to 1,200 dollars to replace coil. Dirty condenser coil causing high head pressure trip. Control board failure after 10 years at 300 to 600 dollars. For Goodman furnaces like GMSS92 single stage and GMVC96 two-stage variable speed, common problems include hot surface igniter failure after 5 to 8 years causing furnace not lighting, showing error code with 1 flash, replace igniter at 100 to 200 dollars. Flame sensor dirty causing furnace to light then shut off after 5 seconds, fix by cleaning sensor with sandpaper. Pressure switch failure showing 3 flashes due to blocked vent or clogged condensate drain. Blower motor failure after 12 to 15 years at 400 to 700 dollars. Overall service rates around 10 to 13 percent indicate decent reliability for price, slightly higher than Trane at 8 to 10 percent but acceptable. Regular maintenance with filter changes every 2 to 3 months and annual tune-up at 100 to 150 dollars prevents most common Goodman problems.
