the fan is always on with no load, what should I do? The specs said it has a auto thermostat to control the fan, but it never turns off and i have not hooked up a load to it.

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.

same thing with me too........i bought two. one worked with the fan alaways on.The second never worked even for a minute.....not good...

I have the same problem but it is actually a benifit in my case. I'm using it to power a car stereo in a wood box and the fan keeps the radio cool too. I purchased a "MEANSWELL" power supply for twice the price of this unit and it's fan never comes on and it powers 2 300watt car amps without any problems at full load

I think the auto thermostat just speeds up the fan when under load. I wouldn't worry about it.

some regulated power supplies need a load to operate correctly. apply a load that draws about two amps and see if it operates correctly.

I don't think it was designed like a laptop where there is no fan speed at all until the processor reaches a certain temperature. Mine runs all the time as well, but quiet with no load, louder with a load. The fan speed change is immediate too which shows to me it is load driven, not temperature driven.

I run a car stereo setup off of mine in the man cave. My fan runs all the time. But I just put a 12v fan controller on it and a bigger fan. Fixed the problem if you're a DIY'er

Mine is always on with no load as well but also pretty quiet. It will ramp up a lot under load. I don't find the no-load noise too much but under load it can be pretty loud.

So is mine. I think that's just the way it's designed. Having the fan thermostatically controlled doesn't imply that the fan should necessarily be off at no load.I run mid-power radio transceivers with this supply. It's pretty apparent just listening to the fan speed whether the radio is idle, transmitting at 5W, or going all out at 100W.

Fan does run at all times, however it appears to be thermostat controlled and will only really spin up when under load. Even then though when I am using this unit its pretty quiet and never really gets hot.

I have incurred the same issue. What has worked for me is before turning unit on, make sure the heater and temp control are off. Once the fan starts moving, then turn on the heat and temp.

While running on the automatic thermostat feature, does the fan stay running constantly? Will it shut itself off at a time setting? Can you set it shut itself off after four hours of run time?

Mine never shuts off unless I get up to turn it off. If it's supposed to have a thermostat, it doesn't work.

The fan was always running on mine. It came with a giant green sticker with leaves on it, so maybe there's a setting for that I missed, but I don't think so. I ended up selling mine so I can't check.

You can use the switch for the fan on "automatic"--on-and-off or "on"--where the fan stays on all the time. I actually use that to keep the temperatures more moderate. But my mom and mother-in-law like the automatic better. Maybe that is what you are experiencing?

Mine does this too, I was told that the fan is turning on and for some reason it is surging. It only does this when in standby mode, does yours do it when in use as well or just stand by?

Did you make sure the temp +/- is set to the temp you want? Every time my power goes off or o unplug it, it resets itself and I have to reset the temp to blow cooler. Also, there is a setting to blow just room air around. Make sure you aren't accidentally on that. Download a booklet and see where the settings should be to blow cool. These things don't have freon, do they??? If so, it could need coolant. When you cleaned it, could you have a loose connection inside somewhere? I've never had trouble with mine, like others seem to. But usually it is because people aren't draining theirs, but trying to use it with it plugged up. And even though they say they'll work that way, they don't. The water must drain. I really love this thing, but using it is complicated.

Is the compressor running or just the fan/coil unit after the temperature is reached? Does it cut off after a couple of minutes? If it just keeps running, it sounds like it might have been wired incorrectly, assuming the "Fan" switch isn't in the "On" position (if it is, switch it to the "Auto" position). If it just continues to run for a couple of minutes, I think the thermostat is likely programmed to do that as a (mildly misguided) effort at efficiency by taking advantage of the low refrigerant temperature that lingers a bit after the compressor has shut off. I actually don't have this model (and am not sure why Amazon thinks I do), and I am going from the behavior of the model TX5000Ua that I do have.

You can easily turn it on/off manually. When the fan is running it will only stay on for the set time interval.

Fan runs all the time. Thermostat regulates temperature in heating and AC mode.

I didn't see anything in the manual about just programming the fan - you have and 'auto' and 'manual' setting on the fan switch - auto has the fan come on only when the heat or cooling comes on - manual has the fan run constantly with or without heat or cooling until you turn it off -

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

My need for the fan is for an audio amplifier that during warmer days would automatically shut down after 20 to 30 minutes. I'd wait 20 minutes and i was able to turn the amp back on. Since it was an over heating problem I installed the fan. I connected the fan's power cable to the amplifier so when I turn on the amp the fan goes on, amp off fan off. This works for me, maybe might work for you instead of running 24/7.

There's a dial that turns on the fan first then the next two settings are heat. Then you turn it all the way back to turn it off. Hope this helps!

There are actually two thermostats for the fan. One is in the fan itself and turns on at 100F. There is a separate thermostat which is taped to the fridge burner tube and closes or opens the flow of electricity, that one turns on at 140F. Both thermostats need to be on to activate the fan. I had issues getting the fridge burner tube thermostat close enough to the burner to reach 140F so I just wired in a manual switch in place instead for that one.The fan works great. The difficult part of the install for me was that I had to remove/reinstall the fridge vent at the roof. That was the only location where I had enough space to fit the fan.
