Hello I have my freezer outside on my front porch an it get a lot of sun out there. I notice the other day than my temp controller was in the sun light an the lcd or led display on the controller was flashing other number’s when displaying the differential. But when it’s out of the sun light it act normally even under room light
yeah, just damn hot.
my handheld thermometer display will do this if I leave it over a boiling pot too long.
