SOURCE: Coleman furnace blower runs continuously

You should be seeing 120 volts to the igniter. Anything less requires either a replacement of the transformer, start relay or control module.

SOURCE: Ihave a goodman GMPN furnace. The blower will not

Maybe not! there is a limit switch that has opened not allowing power to pass and start the furnace. You will need to tale a Ohm meter and follow the wires thru any safety switch. In your case, it may be the thermo-disc near or over the burner box. Jump it out to test it. Now why is your blower not working (which could have been the reason why the thermo-disc opened)? Once you find which safety switch is open and you have jumped it out, take a jumper wire and jump between the R and G terminals on the circuit board. This should start your fan. If not, either the fan is stuck, the fan motor is bad or hopefully noy; the circuit board is bad.

SOURCE: Main blower fan is not starting on my York Diamond

Hi,
Check to see if the blower motor is actually getting power to it...You will have to check for power on the heating speed terminal... and the neutral wires....you should have 120v across those two wires....
If you have power then the motor is bad...if no power then the heating relay went bad on the circuit board and you will have to replace the circuit board...

That is a common problem as those relays are often to light and wear out...

Just realize that without an electrical meter to trace things through you are really just grabbing at possibilities and not really able to correctly diagnose your problem...

My '93 suzuki sidekick automatic transmission 4 wheel drive after warm up "overdrive off" starts flashing on and off and when on the drivetrain stops working
The O/D light's flashing means there is some kind of transmission trouble.

The codes are..

Trouble Code (1) Probable Cause
12 ............................... System Operation Normal
21 ..................... No. 1 Shift Solenoid Open Circuit
22 .................... No. 1 Shift Solenoid Short Circuit
23 ..................... No. 2 Shift Solenoid Open Circuit
24 .................... No. 2 Shift Solenoid Short Circuit
25 ............................. TCC Solenoid Open Circuit
26 ............................ TCC Solenoid Short Circuit
31 ............ Vehicle Speed Sensor Open Or Short Circuit
32 ................ Throttle Position Sensor Short Circuit
33 ................. Throttle Position Sensor Open Circuit
34 ................ Defective Park/Neutral Position Switch
36 .............. (2) No Signal-Both Vehicle Speed Sensors
(1) - Check listed component for probable cause. Also check wiring and connections of specified component.
(2) - No signal from both transmission and speedometer mounted vehicle speed sensors.

If a trouble code is present, OD OFF light will flash a trouble code. The number of flashes will equal first digit of trouble code. After a one second pause, second digit will be displayed. If more than one trouble code is present, next trouble code will be displayed after a 3 second pause. Smallest number trouble code will be displayed first. Trouble codes will be repeated.
Hope this gave you some insight on the issue.

1993 goodman status light 4 times blinking
Witch blower is running, the inducer or the systems blower?
System blower could mean the the high limit is opening and shutting down the systems gas train, I would check this out first.

The other problem could be with the pressure switch for the gas train, it is supplied from the inducer motor, check to see if it is operating fully.

HSI boards do go from time to time, this sounds more like a system control problem.

My furnace the burners light and come on and heat up the unit. But the fan never kicks on and blows. The fan itself works because I can turn it on manually so I know it's not that. The trouble code...
The manual selection on the thermostat bypasses the fan relay. When in Auto, the fan relay turns on the blower. You are probably looking at replacing the circuit board. As far as the three blinks, on the reverse side of the front panel there is a wiring diagram and error code chart. It will give you a starting point where to look for a problem. The three blinks could indicate an open limit because the blower is not operating. Keep the blower on manual and let the furnace run normally until you can figure out what the problem is.

Burners not firing & LED flashing 4 times
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.
A typical limit looks like this: themobilian_1380.jpgConsult your furnace schematic to determine how many of these puppy's are wired in and around the furnace. Make sure they all have continuity. Have the power OFF before you reset the limit. Ouch!

Somewhere in your furnace all of these flashes have a chart you can consult usually located on the backside of the blower cover.

Sorry to read about your problem, I hope this helps you out.

Circulator blower runs continuously. No furnace operation. Integrated control module diagnostic LED is flashing SIX (6) flashes.
6 FLASHES
1 Rollout limit circuit is open.
2 Flame rollout. i? Misaligned burners, blocked
flue and/or air inlet pipe, or failed induced draft blower.
3 Loose or improperly connected wiring.
4 Check burners for proper alignment.
5 Check flue and air inlet piping for blockage, proper length, elbows, and termination. Correct as necessary.
6 Check induced draft blower for proper performance. Replace, if necessary.
7 Tighten or correct wiring connection.

Turn power OFF prior to repair.
i? See i?Vent/Flue Pipei? section for piping details.
i? Ensure the correct pressure switch replacement is used.

THIS IS A GAS PRODUCT, INCORRECT REPAIR CAN CAUSE A EXPLOSION, AND DEATH CAN OCCUR. IF YOU DO HAVE THE PROPER TOOLS SUCH AS MANOMETER AND LEAK DETECTORS, I SUGGEST YOU CONTACT A SERVICE COMPANY

My Goodman GMP 125-4 furnace has 4 blinking lights and we currently are unable to get it to come on. What might be wrong?
if this is an error code and you mean that the light blinks 4 times then it is the limit circuit. This could mean either the high limit or a roll out switch is open. the limit switch is right in the center of the furnace above the burner and roll out switches are probably somewhere around the opening of the burner. Follow the wires from the limit to find a roll out switch cause they are in line with each other and the rool out switch could have a button to reset it. However if the roll out is not tripped then you could need to change the limit. Only way to know is to check for continuity.

Furnace ignites when thermostat calls for heat, runs for a few minutes and the burners extinguish, repeats... changed flame sensor, nodifference, saw 4 quick red flashes evry few seconds after burners...
You don't say if the blower is coming on, no blower would cause the limit to open. By the way, the limit is internal and auto-reset, not the manual reset roll out switches on the burner assembly.

Goodman Model GMNT100-4 Auto Power Down and Up until Temp.
Keep in mind all furnaces and circuit boards are not the same. Look on the back of the door to the blower compartment. You should find the list of diagnostic codes. Look up four blinks it should narrow down the problem. Although from the discription you gave it sounds lie the high limit control. When a high limit appears to be acting up it DOES NOT mean that the high limit needs replaced. The high limit just may be doing its job. This means that the furnace is overheating. Check your filters. Are all of your registers open? Is your blower set on the right speed? Is your blower going bad? Is the blower motor capacitor bad? Is your evaporator coil restricted? Just changing a high limit switch does not always solve the original problem!
Good luck....

I have a goodman gmp075-3 and it is flashing # 4 code
There is a Primary High Limit Switch towards the middle of the furnace, it more than likely needs to be replaced, very common to go out only after a few seasons. Also, you could have a flame rollout switch tripped that will signal the same code, these switches are re-settable and are located on the outer, top and sides of the burner assembly, they’re about ½ inch in diameter with a red push button in the center and two wires “ usually purple” coming off of them.

Hope this helps
