How to test defrost heater
In this article, we’ll explore the steps for testing a defrost heater to determine if it is functioning properly.
Step 1: Gather the necessary tools and supplies
Before you begin the process of testing the defrost heater, you’ll need to gather the necessary tools and supplies. You’ll need:
- A multimeter
- A flashlight
- A screwdriver
- An insulating tape or electrical tape
Step 2: Unplug the refrigerator
Before you begin any work on your refrigerator, be sure to unplug it to prevent the risk of electrical shock.
Step 3: Locate the defrost heater
To test the defrost heater, you’ll need to locate it first. Depending on the make and model of your refrigerator, the defrost heater may be located in different areas.
Some refrigerators have a panel on the back or bottom that can be removed to access the heater, while others may require the removal of the top or side panel.
Consult the user manual for your refrigerator to determine the location of the defrost heater.
Step 4: Test the defrost heater
Once you’ve located the defrost heater, you’ll need to test it to see if it is functioning properly.
Begin by using the flashlight to examine the heater for any visible signs of damage, such as broken wires or burnt insulation.
If you notice any damage, the heater will need to be replaced. If the heater appears to be in good condition, use the multimeter to test it for continuity.
To do this, set the multimeter to the ohms setting and place the probes on either end of the heater. If the multimeter registers continuity, the heater is functioning properly. If the multimeter does not register continuity, the heater will need to be replaced.
Step 5: Replace the defrost heater (if needed)
If the defrost heater is not functioning properly, it will need to be replaced. To replace the heater, you’ll need to follow the instructions in the user manual for your refrigerator and use a screwdriver to remove the old heater and install the new one.
Be sure to use caution when handling the heater, as it may be hot to the touch. Use the insulating tape or electrical tape to secure any loose wires or connections.
Step 6: Test the refrigerator
With the defrost heater replaced, it’s a good idea to test the refrigerator to ensure that it is functioning properly.
Plug the appliance back in and allow it to run for a few hours to see if it is cooling efficiently and if any ice or frost is accumulating on the inside. If everything seems to be working as it should, you’re done!
