This usually indicates an ignition lockout...The heater tried to fire but either didn't fire or a flame was not detected. Check and ,ake sure ignition is good, gas valve is opening and make sure all grounding is intact..

House heater does not blow hot all the time. the furnace kicks on and then shuts of and then the blower just blows cold air. the furnace tries to kick on three times but shuts off, sometimes it works just...


When it blows cold air, there should be an error code blinking on the LED light located on the PC board. Look through a small viewing port in the front panel, then remove the front panel and on the reverse side there should be a diagnostic code chart to help you figure what is wrong.

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.

Hi,
If red light blinks 3 times when tv refuse to power up then check lamp cover that was removed to replace lamp, make sure lamp cover is fixed in its position securely and screw is tight.
Let me know how many times red light is blinking after three second long pause IF it is not blinking 3 times.
Thanks.

The unit won't kick on...It is getting power because the red indicator light is on. Some times it will kick on all by itself after awhile if it is left in the on position. Also, the temperature dial makes...


Hi; If You are good with hand tools,with power off and unpluged, remove the two wires or three always writing down where the wire was connected(color,terminal number on t stat etc.) check for continuity between terminals when tstat is being turned. Keep in mind that one of the terminals is the travelar so one of your test meter leads will remain on the travelar(common).Im sorry this can seem complex to an average consumer so If You have any doubts about You capabilities stop and call a repairman. I am such a person but had to go to tech. school and learn in the field for 25 years.

Tv wont turn


The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.
