What does a red blinking light on the front of the unit mean

A steady red light means that the unit has run out of water or is overfilled and will shut down automatically after the automatic drying period. A blinking red light means that the unit has been turned on without water. Add MyPurFill water, wait 30 seconds and turn on the unit again.

If you see the red flashing light during regular operation, this usually means that the outdoor unit was shut off due to a problem and is currently "locked out" from normal operation. When you see the red flashing light, it is usually in a diagnostic feature to alert the HVAC repair technician to what the problem is.

This is not a split system a/c unit guys. Look at the picture. The blinking light means the air filter may need cleaning. Reset power to turn it off.

red light is stands for hardware boot and the green one is stands for system boot and disc boot. when red light remains solid it means your system is in 0% cpu usage and nothing doing, stop working

when the red light blinks, there will be electric/electrinc circuit failure so get it to a repairer/kodak service.

It sounds like you are actually in lock out. Recycle is when during a call for heat, the flame goes out, the unit will try to restart itself. Hope this helps

slow blinking light means the unit is in DRY MODE.. flast blinking light means some sort of arcing or bad power supply..
if in dry mode let the unit run for an hour and it will stop blinking ..

blinking light means faulty hardware - get a refund or call a helpline

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.
