I just installef this in my truck (I drive 18 wheelers) and the fan keeps turning on for about 2 seconds every 30 seconds. Is that normal?

I asked the same question to manufacturer; they said yes it was normal. Sometimes my fan would not even start until there was enough heat generated for it kick in. I can only surmise that the machine is smarter than me!

I have mine in my truck as well. Mine does that too. I think it is just normal. Sometimes it does it more, sometimes less.

No, I think you may have a bad one. Call Whistler for help. I did for the one I sent back also.

Not sure if that is normal or not, mine does not do that however I run fairly heavy loads (800 watts) so my fan will come on and stay on for 20 seconds or more until unit cools enough. If you are running a light load that may be normal.

Most if not all power inverters will have their fans come on at some point especially when different factors are involved. The room temperature they are operating in or powering larger loads or both. I returned my Whistler for Power Bright instead I just didn't have any luck with the Whistler..... kept beeping for ground fault.... Power Bright no problems

Hello - I realize that you posted this comment some time ago, but I'm hoping you may be able to help me. I bought this fan a couple of months ago but only recently hired someone to install it while I was away on a trip. Turns out my 1948 house has the 2-wire electrical, so my contractor simply purchased a different fan. Now I can't return this one. To use it, what did you do? Did you purchase a different type of remote and if so, what kind? Thank you!

I've never experienced fluctuations in fan speed, mine blows a constant stream of air according to each setting. I suggest if your unit is functioning otherwise you contact the manufacturer.

I wouldn't return that just yet. Don't think this is the same model as mine, but if it's not under a load and running cold the fan is designed to adjust speed automatically and even stop. It may not be broken. That supply being 1,000 watts is going to take some heavy use before you see that fan come on I bet. My 750 stops all the time running 3 mechanical hard drives a ssd and 2 video cards.

This is difficult to answer. First, is this a new unit that has just been put in service? If so, during the setup procedure did you remove the upper housing and insure the filters were not wrapped with a protective cover? Is, then I suggest that you select each of the 3 different fan speeds and see if the air flow changes. If not it may be a defective control unit. In any case, if you can not determine what may cause the problem and this is a new unit I would call the manufacture and explain the problem to them.

Not noisy..but fan cuts off and on every 30 seconds.. does anyone know if this is normal? Only had for 2 months.. It has always done this.

Mine seems to always have the motor running. Mine works great and is not broke. It is not the quietest fan however I have nothing to worry about. I would call then manufacture for more information.

Sorry I cannot help you there. When I bought mine I am not sure if the fan was defective but when I turned it on it bearly, I mean bearly blew any heat, so I sent it back to Amazon and did not get a new one.

Needs a new control modual. Just pull the fuse for the fan to keep it from running until you get your new modual.

Either they have changed the specifications, or your unit is defective. The fan on my unit only comes on when I've had it under heavy load for awhile, then shuts off awhile after the load is reduced.

I installed an intake fan since my power supply has a 120mm fan that is providing the exhaust functionality. That setup seems to keep everything pretty cool (&lt;40 C).

I don't know. If it is new it might be a defect. I have 2 of these units and there is a clear difference in the fan from high to low. Mine have been going strong for a year now....one of them was on my boat all winter running 24/7 and still works great. I'd either check with the manufacturer or send it back. Good luck!

Do you have the fan light pull cord 'on'? Plus the fan speed pull cord is suppose to be on 'high'? It tells you that you need to have them set this way; mine has worked perfectly for the last 3 months. Only other thing I can think of is; that the connections in the remote in the fan are not connected good or they are not tucked up where the fan blades don't bump into it.

Mine did that initially. Up and down between 49 and 53 and the fan kicking in every couple of seconds. I raised the temperature to 55 and it stopped doing that.

I had simular issues and I had the harness that comes with the dash kit plug in wrong temp was in fan fan was in temp I'd double check your hook up a.c. not sure mine works fine after plugging up right good luck

I run it on f2 and it is not any louder than a normal fan. F3 is a little louder but no need to run it on f3. I forget it is even running.

This part can cause this too. It also can cause the fan not to come on at all, it just depends. This is a problem with the vehicles that uses it. It is just a bad set up. The new part can also cause the same problem. It all depends on air flow.
