Testing electric furnace elements.

What you should see assuming a 6 element furnace is the following. Performing basic checks 1. After 30 to 90 seconds the current draw should jump to 42 amps. Water heater not heating.

How to diagnose electric furnaces. Remove the insulation and disconnect the electrical wire at the terminal and use either a multimeter or an ohmeter to test the electrical flow. Inspect the burner element for any damage which can include warping bubbling or damage to the insulation sheath. Testing a conventional element 1 know the resistance of the element should be this can be calculated using known values.

Check fuses element sequencers thermostats and transformer duration. When the thermostat comes on the meter reading will jump from zero to 21 amps as the first element comes on assuming a 5 kilowatt element which is the most common. In this video i show how to use basic electrical troubleshooting methods to diagnose problems with electrical furnaces. Also check the terminal ends for any rust dirt or corrosion.

This is a fairly simple test but one that. Check to see if the element is physically. Look at the top and bottom of the oven to find your elements. If you find some clean the terminal ends with a fine sandpaper or a piece of steel wool.

This is so whether testing upper or lower heating element. Turn your oven off and let it cool if necessary. R v x v p where v is the voltage powering the element p is the power the element uses and r is the resistance an example calculation is shown in the tips section. Turn the oven on and see if the heating elements glow red or orange.
