SOURCE: Heater will not ignite

The igniter should have 120v if it is Hot Surface Igniter (HSI). You may be having a problem with gas pressures. Possible transformer problem also if you changed that with other parts.

York furnace code 7


The error 7 shows that the gas failed to ignite. That is because the sensor does not sense any flame. This can be because the sensor is dirty. You should look in the area of the jets for a wire that may be purple in color. It attaches to a bare metal probe that is shaped like the letter L This probe extends into the path of the flame from the jets. When it detects flame it tellls the controller that everything is good. When it gets sooty or dirty from use it cannot detect the small electric currents that are present. Clean it with scotchbrite. Error 7 means that the furnace is locked out and wont restart for an hour. You can shut the power off and turn it back on to reset it.

My York furnace sometimes doesn't completely ignite


A noisy inducer probably is headed for replacement.

The igniter can produce a healthy glow and still be defective. Mine had to be replaced with a new, improved one.

The thermocouple could be defective even though it seems to open the gas valve when it should.

The heat sensor in the bonnet could be defective. That controls main blower operation.

The heat exchanger could be cracked.

Any light flashin on the control board? If not then look for a small fuse blown on the board. See lights a flashing count them flashes

A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

Goodman 95 %furnace keeps saying low pressure is stuck. changed out low pressure switch and high pressure switch and still have same problem.


That thang might be sensing a lazy flame. In other words the flames took too long in the board's opinion to quit sensing the flame. Yall probably need to do pressure tap on the gas valve.
Here is a realistic look at goodman fault codes and what to check fer and I am assuming you are not a tech and don't know this already and am hoping it helps:

Bottom dollar: it all goes back to type of gas, the initial setup, the pressure tap. and how it is wired up to begin with.
This will give you an idea where to start I hope.
