This may be a silly question, but how do I tell if this product is working? Sometimes I see a red light come on, sometimes I don't.

No question is silly. It has a built in thermometer that keeps the water temperature at 78 degrees. So make sure you have a thermometer in the tank, if you see the temperature of your water is too low that'll tell you it's not working. If the temperature stays at around 78 and above it's working.

It comes on when it is heating so that the water is maintained at a consistent temperature. The heater does not run constantly however and that is why the light goes off.

i installed one and hardly see the red light - if at all. I looked on line for examples for various examples when i wired mine... and its worked ever since.

Is the red led power-on indicator lit?If so,your problem is most likely with the device.A volt-meter would help.

If the red light is constant, it just means that the unit is working. I bought these mainly for spiders and I haven't seen one inside for 5-6 years now. Good Luck

Press the SRC button to turn it on. If it does not work, it might be bad wiring or problem on the product itself. There is not many reasons that might cause it to go bad

It would seem the red light would be on when the lights are on. But, mine as yours, the red is in stand by or off and green when lights are turned on.

Red light indicates power is on to mat. Check other GFI's in circuit if the red light doesn't come on when you hit the reset button.

Red light just shows that power is on. When the light is blinking it is charging. It will be steady green when it's fully charged.

If the light is turning red check the sensor. If ita not turning on at all, it could be a circuit issue.

Check that the battery is 1) good, and 2) installed in the correct direction. If it does not turn on automatically when these are correct, then the unit may be faulty.

I think it means something is wrong. the red light should flash continually then the green light will come on occasionallyand be a solid light. -

On my unit the light is red, and it starts flashing red when I place a drained battery into it for charging. Once the battery is charged it turns green and stays green until I remove the battery to use it.

Is sounds like it is defective. Mine charges and the red light goes out and turns on real easy.

The red light should go off when fully charged. If it doesn't you could have a defective battery that never reaches full charge. Try another battery before you conclude that it is a charger problem.

The red light indicates the unit is working. Most people do not hear a sound coming from the unit. If the red light comes on when the unit senses motion, it is charged and operating. All of this is in the instruction pamphlet.

As soon as you plug the light into the solar panel cord a small little red light should come on ( in the light). If not something is wrong with the cord, connection or the battery.The battery is in the solar panel case. You might check to see if its pluged in or hooked up. Good luck Ken

Does the light come on at all? If no red light comes on when any of the 3 buttons are pushed--1--change out the battery 2--check that the battery is installed properly with respect to polarity (+/-)
