If the external pump does not turn on at all during a cycle, use your multimeter to check the voltage at the pump outlet socket on the back of the furnace. If 120V/230V AC is not present when the vacuum stage initiates, the internal relay on the power PCB is faulty and must be desoldered and replaced.
S (Closing Time): Vital for drying the ceramic before the muffle closes. t (Heat Rate): Degrees per minute. T (Firing Temp): The peak temperature. H (Hold Time): How long it stays at peak temp. Common Issues and How to Fix Them ivoclar programat p90 manual fixed

Provides a fully automatic vacuum ceramic firing process with microprocessor control.
Clean the sealing rim: Dust or debris on the rim (69) can impede movement.
