We bought to and ran them to the tanks on heavy duty extension cords-neither will turn on. What could be the issue?

I think they are temperature activated. They may need to be at or below freezing before their thermostats turn on.

I also have my tank heater hooked up to a lo-ong extension cord. It has beautifully survived a very cold winter in Colorado. Check all your extension connections. Did you check your fuse box? Your electric outlet's reset switch?

If you are running them on same circuit maybe breaker has kicked out. Or if you are running them off a strip it may have tripped also.

My works fine but I just had to replace my ground fault outlet.Not sure if it blew from the tank heater,fence charger on age.Check the outlet.If not that perhaps you received defective ones

I know I'm jumping in real late, but this is a good topic. The manufacturer wants you to send them in for repair. If your unit is out of warranty and you are at all mechanically inclined, you can save yourself some money. Go to UTUBE and watch videos on how to do it yourself. It uses common batteries.

Leave them plugged in for an hour or so and recheck them. I believe I had a similar issue with these initially. I'm anxious to hear if this works for you. I've been really pleased with the lights I am using in our house. Helps so much at night.

Mine went bad and did this same thing, I can hear the relay click but no continuity thru the terminals... Might be that you have a defective unit. Mine lasted a few months pulling about 3 amps at 12 volts for about 5 mins a day. I was running a bilge pump to water my garden from a rain barrel.

I find they did and the batteries I had also exploded. I'm not sure if that is a cheap battery issue or a heat issue or that I left them with the switch on the ON position for 3+ months without using them.

Make sure it's warmed up to the green light comes on then try. Also make sure black tube that feeds the machine is all the way to the bottom of tank as well. If making a loud noise before green light comes on its deff a defective product send it back asap, that's all I can help with there.

I agree with the reviewers below. Try changing the batteries first, then make sure the lamps are fully charged. If that doesn't work, return them.

I had similar trouble. Was about to return and them it suddenly turned on. Have no idea but it has been a year since and working fine. Touch wood.My suggestion - unplug and try after a while. Nothing scientific.

send them back or there is supposedly some type of connector spray that might potentially elevate the problem....I sent mine back

try removing the batteries if its not wired thru the house current. and replacing them with fresh batteries. Jeff D.

Turn on by just twisting, but there is a black disc inside to protect the battery so you must twist it open first, remove the black disc then they should work just fine - mine did. Hope this helps

The tubes should be fully lit up no more than 30 seconds after you turn the power on. You might want to purchase some new tubes because it sounds like they were damaged either during the shipping process or they were defective. In particular, if you bought it used do you notice a lot of metal coating on the top of the tubes? If so then those ones might be burned out already. But if you have the tubes tested and they are still good then check the power jack-plug as Shikai Liu suggested.

The ones mine came mine with turn on right away, but I haven't used them that much yet. Sorry you are having problems. I would call Hunter and see what they say or can do about it.

At first mine did not work. Left it plugged in a little while and now they are fine. Maybe check the outbound voltage

We had the same issue . Tried new batteries and different chargers. Finally returned them all!!

Make sure the battery is charged, next turn on switch under the tank, its the larger one, on the transmitter turn that on and the press the key symbol. If this fails take the tank apart and check wiring connections . good idea to watch a demo in taking it apart on u tube. I took mine apart and rearranged the wiring and upgraded it. It works great. Any broken parts can easily be replaced through amazon or ebay

I dont know - mine worked with zero issue. They are prob defective. Have you read the directions fully and followed them? If so, then return!m If not, try that first.
