Q: how did you diagnose the problem to the element?
Many thanks!

Brent, Check the resistance of the 120 VAC, and the 12 VDC connections to the heater. Below is a cut from the RM211 manual:

In the upper right of the wiring diagram are the heaters. The manual says that the heaters are 95W.
Power = Voltage x Current
Power/Voltage=Current
95W/110V=0.86Amps
Voltage/Resistance=Current
Voltage/Current=Resistance
110V/0.86A=128 Ohms
So, from the black wire to the red wire, there should be about 128 Ohms.
The process above can be shortened by replacing Current in the first power formula with V/R or P=V²/R this is rearainged to solve for Resistance:
R=V²/P
R=12²/95
R=144/95
R=1.52 ohms
So, from the brown wire to the black wire, there should be about 1.5 ohms.
Below is a picture of where this terminal strip can be found:
