Defective heat pad
I believe I have a defective heat pad. I tested resistance which was 0. Is there anything else I should test before ordering a replacement? Any experience on whether they would provide a replacement? I took delivery of the printer in December.

Update: looks to be a blown thermal fuse on the heat pad. The fuse blew at 50c when the bed was heating to 70c.
It happens especially when the ambient temperature is low. I have a box full of spares.
If the fuse blew then the resistance would be infinite, not zero. Were you measuring while disconnected?
