    Problem solved. I did not observe the red led on the control board carefully. It flashed 2 times repeatedly. Problem according to the manual is the "Pressure Switch is open with Inducer on". Turns out that the vacuum tube between the Inducer & the Pressure switch was worn out & was not making a good seal. Just replaced the tube with a 6" automotive vacuum tube. Viola! the furnace fired up a little bit after I turned on the power, turned on the gas & turned up the thermostat.

SOURCE: my furnace tries three times then red light blinks once

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Your furnace has a diagnostic chart on the reverse of the lower panel incorporated in the wiring diagram. One blink tells you that it is a failure but wont tell you where to start looking.

Nissan pulsar 1987 n13 the ECM light came one and the car cut out and won't start again and I need to know where the ECM is


Hi, the computer is under the passenger's seat. Code extraction procedure is pasted below.


READING CODES Modes will not switch while the engine is running. The ECM automatically switches to MODE I when the ignition is switchedOFF.
1984-90 Vehicles With Dual LED System
The self-diagnostic system has 5 modes. To switch modes, switch the ignition ON and use a screwdriver to turn the mode select switch through the access port on the ECM. The inspection lights will begin to flash. When the desired mode has been entered, turn the screwdriver fully counterclockwise. The red LED and green LED perform different functions in different modes.
Mode I-
This is the normal vehicle operating mode. The green LED will indicate loop status. If the green LED is not blinking when the engine is running, the vehicle is in open loop, or the HO 2 S, O 2 S, or sensor circuit has a malfunction. If the green LED is blinking, the vehicle is in closed loop. If a malfunction takes place, the red LED and the MIL will glow, indicating a malfunction has occurred.
Mode II-
Both the red LED and green LED are used to monitor mixture ratio feedback control. The green LED will function as described in MODE I. If vehicle is in open loop, the red LED and green LED will remain on or off. In order for results to be valid, vehicle must be in closed loop. In closed loop, the red LED remains off if the system is running rich, comes on if the system is running lean, and blinks at the same time with the green LED if system is within 5% of the exact air/fuel ratio.
Mode III
-When this mode is accessed, the codes stored in the ECM's memory will be flashed by the green LED and red LED on the side of the ECM. The red LED will light first. This is the first digit of the trouble code; the green LED will flash next, showing the second digit of the code. For example: 2 flashes of the red LED followed by 1 flash of the green LED corresponds to Code 21.
Mode IV-
This mode is used for checking the throttle plate (TP) switch, starter, and vehicle speed switch status. When the TP switch or starter switch is activated, the red LED will briefly flash as the status changes. For VSS status, the green LED will remain off when vehicle speed is less than 12 mph (19 km/h) and come on when vehicle speed is greater than 12 mph (19 km/h).
Mode V-
This mode represents a real-time diagnostic test of the crank angle sensor, ignition signal and the mass airflow signal. The malfunction code will be displayed only when the malfunction occurs and will not be stored in memory. The output code will appear as a single or short string of pulses. Count the number of pulses for the malfunction code.



1 pulse-CMP sensor signal lost or noise in signal 2 pulses-MAF Sensor signal abnormal 3 pulses-Fuel pump circuit shorted or open 4 pulses-Ignition signal lost

I have a Coleman Furnace Model G8T10016U4B11A, the red light flashes twice and I get no combustion blower. Can anyone suggest a solution? Is it a bad board?


Your combustion motor is the very first thing to cycle when theres a call for heat. Look at your access panel. There should be a LED status indicator chart. It will tell you what the flashing LED means and what your most likely problem is.

My central heating is on lockout and the burner is with red light


A sampling of various 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 Goodman 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.

Immobiliser is not turning off and not allowing the engine to start


is it a stick immobiliser?
If your vehicle does not start and the LED continues to flash while the Ignition is 'ON', this means that the Immobiliser system has not recognised the transponder stick.
Simply turn the Ignition 'OFF' then back 'ON' again. If the Status LED continues to flash, move the transponder stick closer to the key barrel until the LED stops flashing and turns 'OFF'.
If the transponder stick on the key ring does not disarm the immobiliser or the
transponder stick is misplaced, you can override the system by entering a 5-digit override number. Each vehicle has a unique 5-digit override number. This number is recorded on the
customer’s owner’s manual. If the customer loses their owner’s manual / override number, the number can be found by locating the vehicle’s Daewoo Stock Number (D.S.N). The customers override number is the last 5 digits of their D.S.N.
9748811.jpg
Overriding the system using the example 5 digit code 2,1,0,6,2
Important Note: 10 flashes of the Status LED represent the number ‘0’.
1. Remove the Transponder from the Key Ring.
2. With the system armed (LED flashing slowly) Turn the ignition ON/OFF 5 times, with the final position being off.
3. The LED will turn solid red for 2 seconds and then begin to flash.
4. When the LED flashes twice (2), turn the ignition ON. (number 2 was entered)
5. Turn the ignition OFF and wait for the LED to flash once (1) and then turn the ignition ON. (number 1 was entered)
6. Turn the ignition OFF and wait for the LED to flash ten (10) times and then turn the ignition ON. (number 0 was entered)
7. Turn the ignition OFF and wait for the LED to flash six (6) times and then turn the ignition ON. (number 6 was entered)
8. Turn the ignition OFF and wait for the LED to twice (2) and then turn the ignition ON.(number 2 was entered) The LED will turn solid red, which means the system is now overridden and the vehicle can be started. If an incorrect number is entered in, wait 11 flashes then start the procedure again.
NOTE: This is a one-event override. Once the ignition is turned off, the vehicle will passively immobilise after 30 seconds. If your 5 digit override number does not override the system, the chances are that you entered the wrong number. If this is the case, you’ll need to re-enter the override number
and try it again.
