Regular calibration and maintenance are essential to ensure the optimal performance of the Ivoclar Programat P90. The following steps should be performed:
The Ivoclar Programat P90 made its market debut in 1987 and was the first Programat furnace to feature a membrane-sealed keypad. It came with an official operating manual that guides you through the furnace's physical assembly, programming, and usage. Although the P90 is a legacy model, its manual is still available through various channels.

: The firing chamber temperature (T-value) is lower than the actual temperature. This often occurs if the furnace hasn't cooled sufficiently between cycles.
Turn off the furnace and locate the vacuum pump hose at the back of the unit. ivoclar programat p90 manual fixed
Select the automated Silver Calibration Program from the P90 menu interface.
If the muffle and thermocouple pass testing, check the SSR on the main power board. The SSR acts as an electronic switch to route high-current power to the muffle. If it fails in the "open" position, the furnace will never heat. Look for visual signs of scorching or use your multimeter to check for input DC voltage from the control board during a firing cycle. 3.
