I bought a broke cloud SERIAL # below 250. Red light comes on but never heats up.
I first removed the silicone sleeve. I removed it with a hair dryer but it left a bit of residue behind.
Using MEK I was able to remove all the residue from the sleeve and a little paint.
Take out the eight screws with an allen wrench and you expose the circuit board and the
wiring. Electronics are isolated from heating unit.

THE PROBLEM
Stainless steel wire has come loose from the stainless steel(?) pad. One side of the connection
to the ceramic heater. It looks like this wire was welded with a single point. Perhaps an
induction weld. Very weak connection for something that goes through such heating and
cooling stress. This is not connected like most heaters. Most heaters have a mechanical
connection a fold over or a crimp and do not depend on a single weld point.
The person I worked with too fix this was a master welder but we did not have the setup to do
a weld though we might try that next time. We attempted to use silver solder to connect
the wire to the plate. This was very difficult to do as however the original connection was
made it made it very difficult to get the solder to tin the plate. However with application
of a torch directly we finally were able to get it to solder. Unfortunately the heat that
we applied broke the ceramic heater. We expected the glass to break. However it still broke
and the cloud is easily pronounced dead.
Attempt to reattach the wire:
That's EXACTLY what happened to mine. See ceramic, although it can handle extreme heat it can't handle uneven heat. We got it to solder but as soon as it started to cool the wires broke loose again. Ultimately the only way they can be fixed was an internal replacement in it's entirety.
I look forward to the EVO - I feel confident that this was the biggest flaw in the original design and that's why their moving on to a new unit.
What I hope they are doing is using a cuff around the heater that would allow unattaching and re-attaching with ease.
