Goodman gas furnace code EE4: Flame sensed with no call for heat

Gas furnace, Canada and United States

The control senses a flame when there is no call for heat. The inducer and circulator blowers run continuously and the furnace does not operate.

This needs a licensed gas technician. There are a few safe checks you can do first, marked below. Anything inside the unit is a job for a professional.

This involves the gas supply or burner. Only a licensed technician should open the unit or work on gas parts.

What causes it

  1. A short to ground in the flame sensor or its wiring.

    Book a licensed gas technician

  2. A burner flame is lingering after the burners should have shut off.

    Shut off the gas to the furnace, then the powerYou can do this

    1. Close the manual gas shut-off valve on the gas pipe outside the furnace first.
      If you smell gas, do not touch any electrical switch, do not use a phone in the building and do not try to light anything. Leave and call your gas supplier from a neighbour's phone.
    2. Only then turn off the electrical power to the furnace. Goodman says to shut the gas first whenever the furnace overheats or the gas does not shut off.
    3. Leave the furnace off and book a qualified servicer.

    Book a licensed gas technician

  3. The gas valve is slow to close.

    Same check as above: Shut off the gas to the furnace, then the power

    Book a licensed gas technician

How to read this code on your unit

The code shows on the three-character display on the furnace control board, which you can see through the sight glass on the blower compartment. IdL means the furnace is idle and normal. A blank display means the board has no power or has failed.
