Hello Forum Members I have an ancient,1980 vintage Thorn Olympic 38/50B boiler, (Great Unit, just keeps going). I had to change the thermostats/timer unit, this unit has a slightly different clock which uses tappets, these are removed and slotted into the outer ring to set the on/off time. Unfortunately 2 of these tappets are missing (1 Red & 1 Blue). Can anyone tell me if these tappets are still available. Thank you for any help given
Have you tried eBay for the exact model programmer you have? Fair chance you'll find parts, or a second-hand unit to crib from.
(Post a photo - and make/model - of your unit, and I bet KIAB will have an answer in less than a hour... )
