@Quattro no the voltage drops to 5,8V when the fan is connected and if i remove the fan the voltage is 24V

@SIam can i replace it ?`its the mosfet from fan1

@SIam the next Port worked, so is the first one broke ?

@SIam doesnt changed anything tried freq 10000 and freq 100 still only 5,8V and no spinning fan

@bearer i measure the 5,8V at the fan connection but the cable is not the problem because when the fan is connected to the always on fan port i can measure the 24V at the fan

@SIam i try it out tomorrow

@SIam no a normal 40x40x10 24V Sunon fan...if i connect the fan directly to 24V it runs normaly

Hello,

i have a 24V fan wich should be controlled by the temperature, but when the temperature 45° reached the fan doesnt spin.
Here are the config lines:

First the lines from the config.json: "fans":[{"value":0,"inverted":false,"frequency":500,"thermostatic":true,"heaters":[1],"trigger_temperature":45},{"value":0,"inverted":false,"frequency":500,"thermostatic":false,"heaters":[1],"trigger_temperature":45}]

And here the lines from the config.g: ; Fans
M106 P1 S1 F500 H1 T45 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P0 S0 F500 H-1 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned off

The temp controlled fan is pushed into fan 1 and the other fan in fan 2

Another fact is that the voltage decreases when i plug in the fan, before there are 24V and if the fan is plugged in there are only 5,8V.

I hope you guys can help me...thanks
