Check the gas valve some can be really finicky, if the setting for pilot is not right bang on in the proper position the button will not go down, and no gas will flow to the pilot. If the button does go down, do you hear/smell the gas flow? If not the valve is toast.Make sure the gas valve to the unit is turned on AND that the service to the house is actually on! I have had many calls for the same issue only to find the gas company locked out the meter!

Fan is blowing in furnace, thermostat raised 10 degrees over ambient temperature and not heating home. Red and green lights blinking intermittently on control board.


Cycle the power first & see if the furnace goes through the normal sequence of order. On a call for heat, the vent inducer motor should turn on and the pressure switch should prove negative draft in the heat exchanger. the board then should power the ignition phase whenter it is hot surface ignition, or spark, you should hear a spark or see the orange glow of the ignitor & the gas valve is timed to turn on. If you have proper gas to the furnace, it should allow the gas to flow through the gas valve & ignite the flame. Once the flame is ignited, the romote or local sensor should sense the flame & the blower then kicks on from the time delay in the board. If you don't have any ignition, then something is wrong with either the ignitor, ignition module, pressure switch, or you have a manual limit that is tripped(this looks like a small 1/2 inch disc with a reset button on it) If you have ignition & the flame lights, but drops out, then your flame sensor is dirty & needs a touch of sand paper to clean it up(this looks like a 3 inch metal rod opposite of the ignitor) Make sure your power is off when you clean the sensor if you need to. Also if there is no ignition & the vent inducer motor is running... if it is hot surface igniton, there is a molex plug on the leead wires to it- disconnect & check continuity- should be under 110 ohms.

Fault code says pressure switch lockout


This more often than not, indicates that your pressure switch is gone and needs to be replaced. Watch the YouTube video for a fuller explanation and heed the warning to use OEM parts! Gas Furnace Pressure Switch Failure and Replacement Amazon com gas furnace parts

Carrier furnace burners will not light.if i blow at the burners it will light.I think maybe bad gas valve or not enough pressure


this sounds exactly like the problem. I replaced a gas valve yesterday in a Goodman furnace that had the same symptoms. I would check it or have it checked with a manometer before you replace the valve. If your inlet pressure is right and you cant get enough pressure by turning the adjustment screw clockwise, it is bad. LP should have @11-13inches of water column coming into the vavle and an outlet pressure of 7 inches of water column. Natural gas should have @5-7 inches coming in and an outlet pressure of 3.5 inches of water column

It wont lite, how do you lite the pilot, where is it located, do you have a manual i have a coleman presidental 3 furnace


There is a window directly above the gas control valve. Either a spring held latch or a screw off cover need to be removed to access the pilot. To light the pilot, turn the knob to pilot and hold down while lighting pilot. The pilot in straight back inside the hole about 10 inches. Use a long fireplace match or rig a wire to hold the match. Once the pilot lights, hold the control knob down for about 30 secs., if it stays lit after release, turn to "On" and operate normally.

I have a EVCON furnace DGAT070BDC. I replace the igniter control, the gas valve and the thermostat. Same problem continues: glow stick works, then the pilot lights works.The igniter control clicks...


You may have a dirty/rusty burner that is clogged or your gas valve
manifold pressure setting may be too low. Normal manifold pressure
is 3.5 inches water column on natural gas furnaces. ( 1 psig is equivalent to 28 inches water column). Pull and clean burner. Also
check and clean pilot assy. including flame sensor (if present).
Please let me know.
