I would be inclined to change out the controller for a Barlett. The kiln itself will be fine but electronics have changed a lot in 22 years and you may be fighting problems due to drying out of compenents, parts no longer made etc. Euclids can help with getting you up to speed with a new Barlett and possibilily zone control.
