On my Goodman furnace light is blinking 3 times
On most Goodman's the three blinking lights indicate an issue with the pressure switch circuit. That can usually mean one of 4 things. 1. Your flue is blocked with debris.2. Inducer motor has failed or is not reaching proper speed to satisfy switch.3. Pressure switch or inducer connections are loose.4. Pressure switch is bad.
Furnace pilot won't stay on.
This can be a number of things;
1. Thermostat is not programmed properly and all your doing is rebooting it
2. Bad electric ignitor for the furnace
3. Wiring is wrong from thermostat to furnace or vice versa
