Testing a Ceiling Mounted Electric Heater

Electric Heater Problem

Electrical Question: Why did my electric heater stopped working?

The electrical wiring connections were easy:

I wired the new heater and it will not work either. I’ve checked the house wiring and it shows 13 volts. I don’t understand what is wrong. I didn’t check the old unit for ohms, but today I checked both units for continuity and they both appear to show open circuits.

This electrical question came from: Dennis, a Handyman from Dallas, Texas.

Thanks for your electrical wiring question Dennis.

How to Test a Heater and Electrical Wiring

Application: Testing an Electric Heater and Circuit Wiring.
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with hand tools and electrical troubleshooting skills.
Precaution: Identify the heater circuit, turn it OFF and then Tag it with a Note before performing any wiring inspections or testing.

Testing a Electric Heater Element and Circuit Wiring

Do not use a tester while the circuit is on unless you fully understand what you are doing and the functions of the test equipment. These electrical components can be safely tested for fault while the circuit is off.

The heating elements will show resistance and should not show give a full open reading.

Possible Electrical Circuit Wiring Problem

  1. Electric heating units place a high load on the electric circuit and the neutral wire connections and splices often produce problems.
  2. Inspect all the electrical wiring of this circuit paying close attention to the white neutral wires.
  3. Burnt or damaged wiring will require repairs that produce clean solid connections that are tight and spliced properly.
