Hi Tony,

reference the re soldering, I always de solder and then re solder, and as I de solder I run the braid along the device pin just a little as I un solder it to give it a gentle rub just to ensure that it has a clean surface to re solder to, the braid/solder mop is inexpensive enough, it also gives you the opportunity to check that the copper solder pad has not cracked and separated from the track this is common with heavier components solder points when a board has had rough handling.
When you stat with the freezer after obvious targets check the SMD resistors on the solder side of the panel, there is a group of these involved in the sampling and feedback loop the Module uses to regulate its output, if any of these are going high in value the Module will shut down into a protection mode.
Let me know how you get on Tony,

regards,

George
