Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.

SOURCE: (HVAC) Furnace Not Igniting Quickly

Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

SOURCE: weatherking furnace flashing 5 times.......

Sounds like it it isn't the igniter but probably the pressure switch. You can only tell by the clicking noises as they system goes through it's safty checks prior to the call to the igniter.

It is possibly the igniter. Check continuity on the igniter to make sure that it is not open.

THE DRAFT BLOWER IS TURNING ON BUT NOT FIRING UP WORKING ALL DAY STOPPED OVERNITE


The induced draft motor has a induced draft proving switch that is a pressure switch , it resembles a silver round flat device about 4 inches across with 2 wires, it will have a tubing attached to it that also is attached to the induced draft assembly housing on a barbed port, this is how the induced draft is "proven" thus giving the A OK to go to the next sequence of operation which is ignition trial period, it will attempt a ignition sequence for about 30 seconds 3 times before it will lock out if it has a circuit board, if so a flashing code will be observed and the legend in the back side of the blower door will tell you the codes meaning.
What is wrong 80% of the time is the barbed port on the induced drafts assembly is obstructed by carbon and not allowing the pressure switch to "sense" / prove the induced draft motor is running. You can connect the pressure switches 2 wires after the induced draft begins, this simulates a operational pressure switch and should begin the ignition phase if all is well, otherwise if all safety's or high limits are closed, then the ignition module is bad.

This is for spark type, if you have a hot surface ignitor look to se if its broken or cracked or has a burned spot visible, if not try testing for 120 volts to it, if you read proper voltage, then the hot surface igniter is bad. 25360510-wil0gxehsfojcry3vcxysbjd-1-0.png

I have goodman GMP series furance the furnance and gas comes on and fires up then goes out flame sensor is good what else could be wrong


Improper ground from control to burner.
Incorrect electrical wiring, check polarity.
Tubing partially clogged between inducer and proving switch.

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.

Hi - I've replaced the thermostat. Furnace runs then shuts off before reaching temperature. Winter in Wisconsin is cold! We now think it's the 1018 series hot surafce ignition control box , but...


When you replaced the stat, did you set it for gas or electric heat?? makes a differance!!
If your heat is starting, the ignition box is doing its job.

The water heater red light keeps flashing rapidly on my Powervent 2 model 41VRP40N. It is not producing hot water and when I read the manual it says it needs more heat. What does this mean. How do I fix...


There are many things to check. The single most important test is for 24V at the gas valve after the ignitor is supposed tp be on. 19 V or less and there is either a bad ground or the ingition control board has failed. (Wire ground problems are a high probablilty)

Here is what the book says:

PROBLEM #1 - HOT SURFACE IGNITOR DOES NOT GLOW RED

(Remember to wait for purge time, 17/34 seconds, on models so equipped).

Possible causes

A. No main power

B. Faulty transformer

C. Faulty thermostat

D. Faulty limit switch

E. Faulty blower interlock switch

F. Faulty hot surface ignitor

G. Faulty ignition control

Solution

Step #1

Perform normal system checks of main power, transformer, thermostat, limit

switch, blower interlock switch, and replace faulty component.

Step #2

With power on and thermostat set at its highest position, check voltage

between "TH" and "TR" on HS780 ignition control. If 24 volts is not present

check output at transformer. If no, replace transformer. If transformer

checks out OK look at other controls in the 24 volt circuit I.E.: thermostat,

limit switch, blower interlock switch. Check for 120 volts between "neut"

(L2) and "120" (L1). Check for 120 volts at the ignitor across "IGN" and

"IGN" terminals on the HS780 ignition module. If 120 volts is present,
replace ignitor. If no, replace the 780 series module

PROBLEM #2 - IGNITOR GLOWS RED BUT MAIN BURNER

WOULDN'T LIGHT

Possible causes

A. Improper ignitor alignment

B. Faulty ignition control

C. Faulty gas valve

D. High inlet gas pressure

E. Polarity reversed

F. No earth ground

Solution

Step #1

Check for availability of gas at gas valve. Make sure the manual valve

upstream of the gas valve and the gas valve are in the full on position. Also

make sure gas is being supplied to the system at the proper pressure, too

high will lock-up the valve.

Step #2

Check proper polarity of "NEUT" and "120" on the ignition control by reversing

the wires, if reversed gas valve will not open. If this does not solve the

problem, replace wires as they were.

Step #3

Check for proper ignitor position.

Step #4

Check for a good earth ground by using a meter connected between L1

and furnace chassis. Should read 120 volts, if no, check and/or repair ignition
ground wire or ignition control mounting screws.
CAUTION POLARITY MUST BE OBSERVED

Step #5

Check for 24 volts at the gas valve terminals; "1" and "2" on a 7200 series,

"M" and "C" on a 7100 series, "TH" and "TR" on a 7000 series. If yes,

check wire integrity or change the gas valve. If no, change the 780 series
ignition module.

That is pretty much all of the troubleshooting required.

Troubleshooting and Repair
Furnaces with electronic ignition systems may be much more efficient than their early counterparts, but they do it largely through electronics. However, there are still some troubleshooting you can do but fixing the problems can involve replacement of parts more so than repair or adjustment. PROBLEM: Furnace burner will not ignite
Possible Solution
  • With a Hot Surface Ignition (HSI) system, if a gas hissing sound is heard for about 7-10 seconds and the burners do not ignite, the furnace will go into lockout mode.
  • To reset turn the furnace power switch off and back on and try again. The switch is probably located on the side of the furnace. A reset button may also be found on the solid state controller. If resetting fails again, proceed as follows.
  • Turn off power and gas to the furnace
  • Remove and check hot surface igniter being careful not to touch the heat element. If it is cracked or damaged, replace the igniter.
      PROBLEM: Furnace comes on for 7-10 seconds then turns off Possible Solution:
      • Turn off power and gas to the furnace
      • Remove flame sensor from its bracket. Lightly clean the surface with fine emery cloth and replace.
      • The problem may also lie in a bad ground or the the black and white wires being reversed (reversed polarity) at the junction box or outlet powering the furnace.
      • The electronic ignition control module must ensure current flow through the flame sensor to ground and if the polarity is reversed in the circuit there is no voltage potential and the flame sensor does not work and closes the gas valve.
      • If the black and white wires are connected correctly and the flame still drops out, then the issue may be a bad ground. Using a volt-ohm meter, measure between the white wire and the ground wire to be sure you have no voltage.

Gas valve lockout


It means that the furnace isn't igniting and for safety the control board is preventing the gas valve from opening. Turn off the power to the furnace for a few seconds then observe what the furnace does in heat mode. Some furnaces will run the blower for a minute after you power it back up. After that see if the furnace tries to come on. If you are still getting the code then one of you high temp limit or roll out switches has tripped. Now is the time for a service tech. Make sure that you check you filter and air flow too. Low air flow means the furnace may be over heating.
The other thing is the hot surface igniter. Look closely at it with the power off. Do you see a white spot on the element or a crack. If so the HSI is bad. It's an easy replacement but DO NOT touch the carbon element with your fingers and be very careful handling it as it is EXTREMELY fragile.

Coleman presidential II furnace blower on and off


Sounds like the flame sensor. But it could be the thermostat. Is the furnace standing pilot or electronic spark or hot surface ignition. I would start by checking thermostat. Turn power off to furnace take thermostat off wall and take wires marked r & w and connect them together. Turn power back on if furnace works then change out thermostat.Most eclectronic ignition Furnaces have a flam sensor, You could take flame sensor out and clean it up with steel wool or wire brush. If you need anymore help just reply back .

Furnace not working. ok light flashing


The flashing light indicates that there is a problem. Turn off the power and then back on. Count the flashes and it will indicate the code to the problem. There will be a time pause between the flash codes. The most common problem is the failure of the hot surface igniter .
