Electrical Projects Table ranges are often used in apartments where full-scale gas or electric ranges are not practical. As you can see from the illustration, the units are extremely simple, consisting of a plug, a thermostat, and a heating element. Some models have two or more elements, and each element is controlled by its own thermostat. Typical ratings are 500- 1200W at 120V ac.

The first phase of troubleshooting consists of testing the range for short circuits. Be sure it is unplugged When making these and other continuity checks, disconnect one lead of the component under test. This procedure isolates the component from the rest of the circuit and assures accurate results. Turn all controls to the off position. Now using a continuity tester, attach one lead to one prong of the cord and touch the other lead to exposed metal parts such as: the stove body, top deck, and front panel. Repeat the test on the other prong of the cord. No continuity should be read. Any reading here will indicate a direct short to the case. Attach one tester lead to each prong of the cord. A reading here will indicate a short in the wiring, or a defective power switch on the unit.
