Instructions to Replace Defrost Heater & Defrost Thermometer

Just got done replacing timer in the Magic Chef MCBR1020W & also have the parts you sent to replace the Defrost Thermometer (part 502413000036) & Defrost Heater (502415000078). The manufacturer has obviously changed the heater as it has several rows of coils vs. the single coil that fit under the fins. How exactly do I replace this without risking breaking the cooper tubing attached to the fins? Actually need some detailed instructions. Whirlpool was of no help.

And on the thermometer, is there a certain way these need to be positioned and/or attached after the heater is installed? :eek:

I’ve attached pictures to better explain my confusion … or at least I think I’ve attached them. Thank you!
