dehumidifier switches to check mode after a few minutes. thermistor?
hi all, i have a EcoAir DD1 CLASSIC MK5 Desiccant Dehumidifier that after a few minutes goes in a check mode then turns off. if i unplug it and then plug it back in it does the same thing. i have narrowed it down to what i think is a thermistor. there are two components that are screwed to the heating element casing [image|1659497] [image|1659498] I think the larger one is a thermal switch and the smaller one is a thermistor?? if i unscrew the two components from the heating element casing the machine works fine and doesn’t cut out. if i leave the thermal switch attached to the element and move the thermistor away the machine works fine and doesn’t cut out. if i leave the thermistor attached the the element and move the thermal switch away the machine cuts out after a few minutes. i think i will try and replace both components, i have found the thermal switch but there isn’t any numbers or codes on the thermistor , does anybody know which thermistor i would need to buy? if it even is a thermistor? i dont believe the heating element is a fault as i think it would ether work or not work if it was faulty, am i correct in thinking that? Also could anyone explain why the machine would cut out if it is a faulty thermistor that is the problem. thank-you for and advice in advance [image|1659503]
