Sounds like you have a hot surface ignitor that is not working. The ignitor is located in front of the burner assembly. It usually takes two 1/4 screws to hold bracket. If you need and more help just reply back to this solution with your questions and i will try to help you

Furnace problems


On - OK
1 Blink - Ignition failure. Check Gas flow, gas pressure, gas valve, flame sensor.
2 Blinks - Closed pressure switch. Check pressure switch (stuck in closed position).
3 Blinks - Pressure switch - failre to close. Check venter, pressure switch, vent blockage.
4 Blinks - Open limit switch. Main limit or aux limit are open. (My comment - Means overheating in chamber. Often result of blocked intake air. Bad filter. In my case, plastic wrap had been sucked into the intake. )
6 Blinks - False flame sensed. Check sticking gas valve.
Rapid continuous blinking - Incorrect twinning, incorrect primary polarity. Reverse transformer secondary leads, reverse primary wires.

Closed pressure switch can be from dirty combustion vents, bad chamber pressure - like missing screws, maladjusted gas pressure, failing pressure switch, loose hoses, moisture in the hoses or fan blades The switch need to be closed to ge the unit to work

Sony klv-v40a10e black screen green light on but 15 blinking red lights after a double power down from electric company


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Have a gmp125-4 furance blower runs all the time checked themostat wires error code 1 blink then 2 then 3 then 5 furance works if you turn power off turn back on when heat kickes off blower comes on gives...


Sounds like limit switch issue. Furnace heats up, high temp limit switch opens, fan will stay on. GMP model is older and do not have the codes.
May be over fired, have airflow problem, to cause the limit to open.
Next time before shutting off power, try to find the limit, it has two wires that connect to a 1.5 x 2 inch card mount to the furnace fire wall. tap on it and see if the blower stops. If so replace the limit.

Try this method for programming. Press and hold the button down on the remote while you press and immediately release the learn button. Do this for each remote.

Have you replaced the battery in the keypad? Try this:

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

Post back with your results.

Bryant Plus 90 Furnace - Blower works fine and intermittently blows warm air but will not bring house to temp set on thermostat... Get a 1-3 error (one blink and then 3 quick blinks of the LED) Thanks


PRSSURE, DRAFT SAFGUARD, AUX-LIMIT SWITCH(WHEN USED)OR BLOCKED VENT
SWITCH(WHEN USED) DID NOT CLOSE OR REOPENED (DOWNFLOWONLY)
If open longer than five minutes, inducer shuts off for 15 minutes
before retry.
Check for:
* proper vent sizing
* defective inducer motor
* restricted vent
* excessive wind
* low inducer voltage(115VAC)
* defective blower motor or capacitor
* defective pressure switch
* inadequate combusstion air supply
* disconnected or obstructed pressure tubing
If it opens after trial for ignition period, blower will come on for
90 sec. recycle delay.
Check your air filter for blockage, check pressure switch for a buildup of moisture. Make sure your inducer motor is turning and creating a vacuum to the pressure switch. Make sure all venting is clear and free of water or debris. Make sure there is no water in inducer motor and all drains are draining.

4 blinks, main limit switch open or aux limit switch open. How do I fix this?


There is a limit switch above the burner with 2 wires going to it. Take a jump wire and jump out the switch to test it, It is 110 volts so be careful. If it fires, that switch is bad and will need to be replaced. There may be up to two more switches on the same circuit. These switches may be reset-able if there is a small dark red button between the two terminals. Why did the unit overheat in the first place. Is your air filter clean? Is the room air blower working? Are all return air grills free of obstructions?

Pressure, draft safeguard, or aux limit swtch did not close or re


The limit switches are two wires that go to a small disk about the size of a dime. There should be a tiny button between the wires. Find all the limits and push them to reset them. The draft safeguard is the one that is located where the flu pipe leaves the unit. Sometimes the limits are stubborn and it's hard to push them in. If you can't get it reset then the limit will need to be replaced but it can be bypassed temporarily by jumping the two wire together. Do no do this as a permanent fix. It can cause death.

limit switch is on the heat exchanger black plastic about 1and1/2 in. by 2 in. with 2 wires going to it , it has 2 screws holding it in take it out and check it with an ohm meter and you should not have a reading if it is good
