After exchange of the spare heater, the oven did not come up to full temperature.
We couldn't get past 135C at 95% heater power.
Verified that both heaters have 20 Ohms resistance, so they are not damaged.
Inspected the heaters visually and found that there was virtually no air flow
out of the oven exhaust pipe. Wiggled the hot air pipe a little and managed to get
a small air flow out of the exhaust (hardly noticeable).
Surprisingly, the temperature increased dramatically! Now 170C is easy to reach.
It looks like the connection of the hot air pipe to the oven is poor.
==>> PLEASE CHECK THE HOT AIR CONNECTION
NEXT TIME YOU WORK INSIDE THE TARGET CHAMBER!
