I bought a nice looking dehumidifier recently from an auction it is designed to operate on 240volts but it has an inbuilt transformer which means it can operate on 110 volts also it has been set permanently to 110 for safety reasons the 240 fuse has been removed this I understand is quite common on dehumidifiers here in the uk as a damp wet safety reasoning.I turned it on in my very dry woodshop and it fired up stayed on for about five minutes thermostat kicked in and it switched off for about four mintes and kept doing this on and off.I suspect nothing is wrong ,but I have never used one and as said the shop is bone dry is this normal like a little refridgerator and is nicely and professionally made.Question is this is the constrant switching on and off correct for this type of machine I just don’t know. ? perhaps if I used it where it is damp it might stay on longer but then I have no idea help please required from the experienced Alistair

A dehumidifier is nothing more than a cooling coil like an air conditioner or refrigerator.

If it didn’t cycle it would freeze up the coils.

I have a mobile dehumidifier for drying lumber. Mine stays on constantly if I set the humidistat to 20%. If the set point was very close to environmental humidity, I suppose it would cycle on and off as needed.

It most likely has a humidity sensor. I think your unit is running and doing its job with the surrounding air then kicks off as it reads low humidity. Your shop is dry so its wanting to kick off. If you want things really dry I would use a second air circulating fan to help move air around your shop.

Can’t help much Alistair on your query but if where you are is anything like Ayrshire this past few weeks then it would be on constantly, what with all the rain.

Hope you get it sorted out Ok.
