Extension cords, ground adapters and power strips with major appliances: what to tell the customer

Manufacturer installation instructions for refrigerators, washers and dryers say not to use an extension cord, and CPSC warns that overloaded cords overheat. This guide covers how to check what you find and how to explain the fix without doing electrical work outside your scope.

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.
