Question about Goodman GMS90703BXA Heater
Unit shuts off on reaching heat setting but ID Motor continues to run. Unit heater and blower sometimes restarts when thermostat signals a need for heat, but other times not and status light gives two flashes to indicate the pressure switch is stuck closed (ID Motor still running). The pressure switch was replaced but still get same situation.

The board is bad. The unit thinks a flame is present, so it tells the blower to come on. Replace the board.

it sounds like the low temp limit switch, the one that cools the furnace down with the burner off and the thermostat open, when it cools to a point the fan stops, the other switch in burner area turns burner off/on, hope this helps
