AndrewMAshton Posted March 12, 2019 Report Share Posted March 12, 2019 Hello, not sure if this is where I should post, but here goes, I have an ecoair dehumidifier, DD122 Classic Mk5 that is playing up, briefly, it switches itself off after 20 minutes running on all three settings, I have checked the manual, no help, after having searched on t'internet it appears it could be a thermal cutout, anybody on here got any advice, experience, wiring diagram before I consign to the tip and buy another, it seems such a waste as the thing is not long out of warranty, cheers, Andrew Quote Link to post Share on other sites
RogerH Posted March 12, 2019 Report Share Posted March 12, 2019 (edited) Hi Andrew, Why not contact the manufacturer, they may have some advice/recall etc. It looks like it is microprocessor controlled so probably heat related - they don't like the heat. https://www.ecoair.org/after-sales-service Roger Edited March 12, 2019 by RogerH Quote Link to post Share on other sites
foster461 Posted March 12, 2019 Report Share Posted March 12, 2019 If it is overheating make sure the air filters are clean. If it drains into an internal container these will have some mechanism to detect a full bucket so that would be another point of failure. Stan Quote Link to post Share on other sites
AndrewMAshton Posted March 12, 2019 Author Report Share Posted March 12, 2019 Hello, thanks for the response, done all the usual visual checks, I think it is heat related as the thing cuts out completely instead of showing a fault light, my next course is to tack down the heat switch, any clues to its whereabouts gratefully received, cheers, Andrew Quote Link to post Share on other sites
RogerH Posted March 12, 2019 Report Share Posted March 12, 2019 Hi Andrew, try and get to the circuit board. Look for the Uprocessor and see if it has anything stuck on top of it. But if you find it what will you do????? Roger Quote Link to post Share on other sites
barkerwilliams Posted March 12, 2019 Report Share Posted March 12, 2019 (edited) Andrew, Here is a generic fault-finding web page https://www.goodairgeeks.com/dehumidifier-keeps-shutting-off/ Also electric motors often have an inbuilt thermal cutout. Sounds as if it is the out-of-warranty detector chip, most things I buy seem to have one of those! Alan Edited March 12, 2019 by barkerwilliams Quote Link to post Share on other sites
Tim Carr Posted March 12, 2019 Report Share Posted March 12, 2019 Hi, It sounds like the dust should be removed from the cooling fins. Tim Quote Link to post Share on other sites
