Ground continuity and leakage check before you leave a repaired appliance

Panels, ground straps and green screws get removed during repairs and are easy to forget. A quick power-off check from the cord's ground pin to the cabinet, plus a check from each hot pin to the cabinet, confirms that the frame is bonded and nothing is leaking before the customer touches it.

Finding an open neutral or bootleg ground at an appliance outlet

A bootleg ground is a receptacle where the ground terminal has been jumpered to the neutral. Three-light plug-in testers cannot detect it, and a reverse-polarity version puts line voltage on the appliance frame. This guide uses meter readings and an external ground reference to find it, then refers the repair to an electrician.

240 V appliance missing one leg: dryer no heat, range half-working, water heater cold

On a 120/240 V appliance the 120 V parts (motor, lights, controls) keep working when one hot leg is lost, while the 240 V heaters stop. Measuring the receptacle or terminal block quickly separates a supply problem from an appliance fault.

Finding a short or leakage to ground in an appliance (meter and megohmmeter)

Leakage from a heater, motor, pump or wet harness to the metal frame is the usual reason appliances trip GFCIs. A standard meter finds hard shorts; a megohmmeter applies a higher test voltage and finds weak insulation that only leaks under real voltage, heat or moisture.
