Kevin S Posted March 28, 2021 Report Share Posted March 28, 2021 Hi I have an old Spaform 4000 elite with a blower relay stuck in blower runs all the time! Does any one know what the relay number is on the pcb board K? For some reason there was a change from K12 Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted March 28, 2021 Report Share Posted March 28, 2021 They are often labeled by the relay. I can't tell from the angle of the pic. Maybe k2? Does your blower have 3 speeds? If so, it is using a triac, not a relay. Quote Link to comment Share on other sites More sharing options...
Kevin S Posted March 28, 2021 Author Report Share Posted March 28, 2021 No single speed 900w, every relay is labelled other than the blower there are two relays not labelled K14 & K12 the set up has 3 pumps 2 of those at high/low speed separate relays all labelled. The board was made with a position K13 for a zettler relay bottom right of image labelled blower, but has solder filling the holes from manufactuer? Originally the blower was intermittent stopping starting I tapped the board to try and find the relay and the blower stayed on and had to unplug. I thought K2 was a possibility I tried to check with the multimeter but could not see the tracks to pick up the pins?! Quote Link to comment Share on other sites More sharing options...
