Gas furnace pressure switch open with inducer on.

The furnace pressure switch sends a signal to the furnace control board that verifies the inducer motor is working. Furnace diagnostics indicate pressure switch open with inducer on what could be the problem. If you get a pressure switch code and the inducer will not come on remove one of the wires from the pressure switch. Furnace nordyne model kg6rc 080c 16b used to work fine before but has not worked since reactivating gas.

The source of pressure switch problems can sometimes be a pain to track down. A gas furnace pressure switch is a safety component that makes sure gas is being vented from a furnace before starting. A furnace pressure switch confirms the draft inducer motor is working. If the inducer comes on the pressure switch is stuck closed.

A gas furnace pressure switch closes to allow current to pass through and start the ignition of the furnace. When a furnace turns on one of the first components to start is the inducer motor. A furnace draft inducer motor vents toxic gases outside. This is not a repair.

Today i am focusing on the pressure switch used in gas furnaces that prove inducer fan operation. The pressure switch must be replaced. When the pressure switch opens the gas valve closes and the furnace starts another ignition cycle because the pressure switch closed after that 1 2 second glitch. Only oem pressure.

Tapping lightly on the pressure switch body may open the switch and the unit may start. The board first checks the switch to ensure it is open prior to inducer call. The pressure switch on a furnace may fail or get stuck in an open position and there are few simple checks you can complete before testing the switch. I recently had my natural gas turned on after being off for a few months.

As noted above the pressure switches used for gas furnaces are almost always normally open. A pressure switch is designed to sense the negative pressure created by the draft inducer motor during the furnace startup and to shut down the furnace ignition if the air pressure is inadequate. If the pressure switch is stuck it does not send enough power to the inducer and therefore the ignition sequence does not begin. The furnace then runs awhile longer and this crazy cycle repeats pressure switch glitches open gas shuts off furnace starts another ignition cycle.
