First inducer fan will come on then the flat surface igniter will come on then the gas valve will open and light. You need to check the gas supply is it propane or gas make sure it is not froze up. either you have a gas supply problem or a bad gas valve.

SOURCE: No heat, trouble shooting light has continious flash.

There is a vacuum sensor on most units tied from the exhaust gas fan to the sensor. Does the unit try to start? If the unit's exhaust fails to pull the switch it will turn off after about 30-45 sec after starting. "IT" thinks it's not exhausting and stops to keep from overheating. Do you have this exhaust fan and rubber hose to sensor? Can you see if that fan is turning on start?

SOURCE: shuts off

Yes. Most likely its the flame sensor. The flame sensdor is a steel rod that sticks into the flame. Usually always opposite the side of the ignitor. Remove it and use some fine sand cloth / paper and clean it shiny and retry it.

Please let em know if this doesn't work. Please give me as high a mark as you can and good luck.

1987 plymouth reliant power loss light

You need to do the on board diagnostics to determine what trouble code(s) it is giving. Here's how: cycle key to On (not start) position, then off, then on again, then off, then on, and leave it in the on position. (leave on after 3rd time on ) Now the check engine light will flash a series of 2 digit numbers, with a pause in between each digit. For example: 2 flashes, pause, then 2 more flashes, would be code 22. 3 flashes, pause, 5 more flashes would be 35. There will also be a little longer pause between the 2 digit codes. You may have more than 1 trouble code, so pay attention and write them down as you go. When you get code 55 ( 5 flashes, pause, 5 more ) that means end of message, or codes. Get back to me with those codes and I will tell you what area the codes are pointing at as a problem. Does the car seem to be experiencing any running problems currently?

What does the error code of 5 red flashes mean?

Code table should be on the back of the panel you take off the furnace. If you can not find it then go to goodman .com and try to get a manual print out online. It is a code for a limit switch being out,such as the air switch or high temp switch,The code will tell the story

I have a Goodman GNP075-3 and its flashing 5

Hi, here is what you need to do. Go to the unit where you can see the flashes taking place. You need to remove the panel to expose the circuit board where the led light is. This door panel may or may not have a small door switch mounted on the perimeter that will kill the power to unit when removed. If you have this set-up, just tape the switch down with panel off to restore power. Now, look on the door panel or in the area of the compartment, and you will find a code chart glued to it somewhere. It will have a list of problems and answers for this units flashes. Depending on how many flashes is taking place, such as 5 and so on, it will tell you where to look with 5 and tell you what is going on, such as a dirty or plugged filter, a inducer motor that is not running, a pressure switch that is open, and many other solutions it could be. These heaters almost trouble - shoot themselves. Check this out and see where it takes you. If it is something you are not sure of, please contact me and I will help you finish solving this problem. This is very easy and you can do it! I will look forward in hearing back from you!

Light flashes three time repeated may fire but burner cycles every few seconds

that is a pressure switch failure code, you can try to clear the barb fitting on the Inducer motor housing that the rubber hose connects to . but without an manometer you cannot test the draft levels to see if the switch is working or if their is a draft problem

Engine service light is constantly on

That's basically your vehicle telling you that there is a problem. Not 100% sure whether in 96 you can cycle key to retrieve trouble codes or not, but you can try. Here's what to try.
Turn key to ON (not start) then off, then on,then off, then on, and leave it on. Have a piece of paper and pen ready and count the flashes of the "Check engine light". It will flash a 2 digit number, with a pause in between each number. For example: flash,flash,pause, flash,flash,flash, would be code 23. Flash,flash,flash,pause,flash,flash, would be code 32. There will be a slightly longer pause in between the codes. When you get code 55, which is 5 flashes, pause, then 5 more, that means "end of message. Get back to us with the results and it will help pinpoint where the problem is and will help cure it quicker, and usually cheaper by taking out some of the guess work. We'll be waiting to hear back.

Air bag sensor keeps flashing

If a concern is detected, the air bag control module will communicate by flashing the warning indicator. A diagnostic trouble code (DTC) is logged by the air bag control module in a nonvolatile memory. For additional information, refer to Diagnosis and Testing in this section.
Lamp Fault Codes (LFC)
Item Part Number Description 1 One flash cycle: Driver air bag trouble code 2 Two flash cycle: Passenger air bag trouble code 3 Three flash cycle: Trouble code common to both driver and passenger air bag circuit 4 Four flash cycle: Safety belt pretensioner trouble code common to both driver and passenger pretensioner circuits 5 Five flash cycle: Driver side air bag trouble code 6 Six flash cycle: Passenger side air bag trouble code 7 Not used 8 Not used

Airbag flashes 10 times misses a flash then repeats

Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.
  • Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
  • If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
  • If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.
Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.
  • If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
  • If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.
Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.
  1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.
  1. Cycle the ignition switch to OFF and then to RUN.
  1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
  1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).
  1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.

My cars engine turns over, but it won't start.

You'll need to determine if it's getting fuel, & spark, if you know how to check it. Also try cycling key on, off, on, off, on, and leave on and count flashes from check engine light. Will always be 2 digit number. For example flash, short pause, flash would be code 11, flash,flash,flash, pause, flash flash, would be 32. After every 2 number set, it will pause a little longer then start again if more codes are present. Try this and write them down & get back to us. These are trouble codes to try & tell you whats wrong.
