Main fan doesn't work

Post by Raztech »

Hello,
I have recently purchased and assembled a Tec 4. Every thing I can test from the control panel works correctly, only the main fan won't start. I have tested the fan and it works so there is no problem with the wires. There is no 12V coming from the motherboard or there is no signal given to start the fan. What can be the cause of this?

Hi Raztech,

Just to be sure, did you connect it to the fan port with description "opt" on the main board?

Yep. I have just reloaded the firmware, but still no working fan and LED lights.

Hi Raztech, we have your printer in house and fix it coming days. The fan transistor of the mainboard is defect.
