This client was concerned because their oven was not getting hot! Upon the diagnostic process we discovered that the heating elements were getting 120 Volts out of the required 240 Volts. Upon further inspection burnt wires and a loose terminal stud was found. Our technician performed wire repair to the Oven Harness, replaced the Oven terminal block, and power chord. To verify the wire harness repair our technician performed what’s known as a voltage drop measurement with his multimeter, this process measures the difference in voltage across two points in an electric circuit (useful for checking resistance in a circuit as resistance will “consume” voltage). This test is much more accurate than a simple Ohm reading because you are measuring a live circuit with current flowing through it. This test is important to ensure circuit integrity, as loose crimps could cause a loss of voltage or generate heat which could result in more burnt wires. In this instance there was a voltage drop of .006 Volts from the power chord to the last crimp in the repair, this is a fantastic reading across crimps and is well within specification for voltage lost over crimps / connectors. Thanks to our highly trained, highly skilled Technician, this clients Oven was restored to manufacturer specifications and is now operating as intended and designed. If you’re having trouble with an appliance, remember Apex, the best way from start to finish!
