Should the operation light stay red?

Flashing means there is a fault, steady red means it is okay?

That can mean the bag is full.

Three blinking lights & door won't close by Candi
(Winston-Salem, NC)
Garage door will not open and close with remotes. Three blinking lights occur when we try to close door. What does this mean? It is a Linear unit.

I will assume you mean that your garage door will open with your remote but will not close. It should close if you press and hold the wall control button until the door is fully closed.

If that is the case, the 3 blinking lights indicate that your garage door's infrared safety beams are not properly aligned.

1) Check that the operator has power. The green lights on the sender and receiver should be lit.

2) If the receiver's green light is on, but the red light is off, the receiver has power but is not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by
mis-alignment or something blocking the beam.

Adjust the safety beam sender and receiver while watching the receiver's red light (stay out of the beam while aligning it). When the red light stays on, the beam is aligned and your garage door should operate normally.

NOTE: If the receiver's red light remains off, check for:

1) Dirt on the receiver's lens,

2) Sunlight shining into the receiver's lens,

3) A short in the safety beam wiring (from staples or at the operator terminals).

red light stays on with no sound or picture,,,

srs means secondary restraint system. e.g air bags and things like that. when it stays on for a few seconds its because it is doing a systems check. if the light stays on all the time then there is a problem. hope i helped.

shellnbarry, As I stated in a previous post the red light flashing means an ink cartrdge is low but not empty. When the red light stays on it means an ink cartridge is empty. You can continue to use the printer until the red light stays on.

that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad

if the light is blue it just means the car is not at operating temperature yet. let the car warm up before driving. if the light is red and only stays on for seconds check the coolant level. could possibly be a bad level sensor also if the light is red
