Heater Contact
Vol. 17 #3, Dec. 1990
After a cold shutdown for maintenance, be sure to check for good contact between the cast heaters and the barrel. Sometimes, during cooling or reheating, the heater can separate from the barrel. This causes local overheating of the aluminum heater, which may melt and fail.
