This ballast transformer restores proper power regulation to the appliance lighting circuit so bulbs operate reliably and safely. Designed for use as a direct replacement to revive dim, flickering, or non-working range-hood/vent hood lamps. What it does:
Checked Magnetron, capacitor, and diode. All checked ok. Magnetron was very low resistance across connections and infinite to ground.
