- Symptom: No heat, weak heat, or intermittent heat
- Problem: Magnetron filament connectors have loosened and,
due to resistive heat, the terminal connections have deteriorated
and burned off.
- Solution: Repair defective terminals as follows:Either
(1) Cut away burned wire, clean the magnetron terminals, and replace
the slip-on connectors, or (2) Cut away burned wire and connector(s).
Clean terminals to prepare for soldering. Solder filament leads directly
to magnetron terminals. Be careful not to apply soldering heat any
longer than necessary
