Goodman mgmt090-3a no ignition
Got home last night no heater on, usually it's the pressure relay hose/metal housing intack with minteral buildup, checked all clear, turned on I hear gas coming on but no ignition, I test it 3 times after the third time finally get led light either blinking 1 time or constantly there's about a second and half dealy between beeps, 1 beep refers to pressure switch, flame sensor or hot surface ignitor, the part number on the HSI is 271N, is it acceptable if a hvac professional used a nongoodman HSI? I searched the part shows up as Norton 271N. Can I use any HSI? Were should I go from here? Buy the part 30.00$ replace? Thanks
