When I turn on the A10 the temperature reading on LCD for the extruder reads 189.
Changed out print head to a new one and same thing.
Meashred the thermister and it reads 110.4 ohms

If I heat up extruder the display will change to 202 degrees but it wont melt the PLA so I assume it is not the correct temperature.

Any suggestions?
Thanks
Doug

Hi，you can unplug the cable of the extruder. If the temperature of the extruder shows -14℃, the motherboard is ok. You need to check whether the connection is intact, or use a multimeter to test the continuity of the cable. If there is no problem with the cable, it is a problem with the extruder.

Thanks for the reply.

With the cabl to the extruder unplugged it still reads 189.

Thanks

Hi，the motherboard is broken, you should replace it.
You can contact the salesperson on the purchase platform for replacement.

Thanks William

Hi
I found a solution to the damaged thermistor. Today I made this adjustment on my A10M. It must be switched to the E0 thermistor to the E1 thermistor and make a small modification of the FW and everything is functional again. I'll give a better description tomorrow. Sorry for my English.
