My kiln controller is behaving strangely in cold weather - what's happening?

If it's particularly cold in your workshop, issues can occur with your kiln controller. Many digital controllers require the temperature at the tip of the thermocouple to be higher than the temperature inside the control box. The controller is effectively the "cold junction" of the thermocouple system and as such must always be colder than the thermocouple itself. To remedy this, direct a fan heater into the chamber of your kiln to warm it for a short time before turning the kiln on and beginning a firing.
