To determine if your heating element is functioning correctly, you can follow a series of diagnostic steps and checks. These steps involve both visual inspections and technical measurements using tools like a multimeter. Here’s a detailed guide on how to assess the functionality of your heating element.
5 Simple Steps to Check if Your Heating Element is Working
1. Visual Inspection and Basic Checks
-
Check the Instrument Indicator Light:
- If the indicator light does not light up after powering on, ensure the plug is properly inserted and check for any blown fuses. This could indicate a power supply issue.
-
Observe Temperature Rise:
- If the power supply and heating elements are normal but the temperature in the furnace does not rise, adjust the set temperature or have maintenance personnel inspect the control circuit.
2. Use of Multimeter for Resistance Check
-
Testing with a Multimeter:
- Place one probe of the multimeter on one screw of the heating element and the other probe on another screw. The multimeter should read between 10 and 30 ohms if the heating element is functioning correctly.
-
Regular Resistance to Grounding Check:
- At least once a month, check the heating element resistance to grounding. An acceptable reading for most furnaces is 90 – 100 ohms. A measurement of 10 ohms or less typically indicates failure.
3. Temperature Sensor and Controller Checks
-
Temperature Fluctuations:
- If the furnace experiences temperature fluctuations, check the thermocouple or temperature controller. These may need recalibration or replacement.
-
Deviation Between Set and Actual Temperature:
- If there is a deviation between the set temperature and the actual temperature in the furnace, replace the temperature sensor or temperature controller and correct the stakeout position.
4. Power Supply and Element Integrity
-
Check for Normal Output:
- If the OUT indicator light does not flicker despite normal output, check the main circuit for issues like short-circuited resistance wires or a malfunctioning heating element.
-
Voltage and Current Checks:
- If the ammeter does not show current but the voltmeter shows voltage, the heating element might be broken and should be replaced.
5. Maintenance and Safety
-
Professional Maintenance:
- Any maintenance or repair work on the heating elements should be carried out by a qualified technician to avoid safety risks and potential damage to the furnace.
-
Regular Cleaning and Inspection:
- Regularly clean the hot zone and inspect for loose connections, damaged thermocouples, or buildup inside gas nozzles.
By following these steps, you can effectively determine whether your heating element is working correctly. Regular maintenance and timely checks are crucial to ensure the longevity and efficiency of your furnace.
