Hardware

2. Geta multimeter, unplug the HeatedBed cable from the Controller, and measure the resistance of the Heated

Bed. The resistance shouldbe inthe range of 60 KΩ– 130 KΩ.If the test value is out of the range, then the

Heated Bed might be broken, replacing it might solve the issue.

3. Check if the circuit is open.Get a multimeter, set it to continuity, and testthe two big pins(see picture below)

inside the connector of Heated Bed cable.

- If the multimeter displays 1 or OL (open loop),then there's no continuity.

- If the multimeter displaysa value of zero (or near zero), and makes abuzzsound, thenthe circuit is

continuous.

4. If previous troubleshooting doesn't solve the problem, then it might be thatthe Heated Bed port on the

Controller is broken. Replacing the controller might solve the problem.
