How to Test Thermal Fuse in GE Dishwasher - Step-by-Step Guide

Thermal fuse is an important component in a GE dishwasher that serves the purpose of protecting the dishwasher from overheating. If the thermal fuse has blown, it could be the reason for your dishwasher not working properly or not starting at all. In this article, we will guide you on how to test the thermal fuse in your GE dishwasher to determine if it is faulty or not.

Step 1: Safety Precautions

Before starting any repair or testing procedure, it is crucial to ensure your safety. Cut off the power supply to the dishwasher by unplugging it or turning off the circuit breaker that controls the dishwasher.

Step 2: Locate the Thermal Fuse

The thermal fuse in a GE dishwasher is generally located behind the control panel or along the inner door frame. Refer to your dishwasher's manual or schematic diagram to find the exact location of the thermal fuse. In most cases, you may need to remove the front panel or control panel to access the thermal fuse.

Step 3: Remove the Thermal Fuse

Once you have located the thermal fuse, carefully disconnect the wires connected to it. Make sure to take note of the wire positions or take a picture for reference when reconnecting them later. Use a screwdriver or a socket wrench, if required, to remove the screws holding the thermal fuse in place.

Step 4: Testing the Thermal Fuse

To test the thermal fuse, you will need a multimeter. Set the multimeter to measure resistance, and touch the testing probes to the corresponding terminals of the thermal fuse. A functional thermal fuse will show continuity, indicating a low resistance value. If the multimeter shows no continuity or a significantly high resistance value, it means the thermal fuse has blown and needs to be replaced.

Step 5: Replacing the Thermal Fuse (if necessary)

If the thermal fuse has failed the continuity test, it is necessary to replace it. Purchase a new thermal fuse compatible with your GE dishwasher's model number. Install the new thermal fuse by connecting the wires to their respective terminals and securing it with the screws you removed earlier.

Step 6: Reassembling and Testing

After replacing the thermal fuse, reassemble the dishwasher by following the reverse order of the disassembly steps. Make sure all the connections are secure and the panels are properly in place. Once reassembled, reconnect the power supply to the dishwasher and turn it on. Test your dishwasher to ensure that the thermal fuse replacement has resolved the issue.

Following the steps outlined in this guide should help you effectively test and replace the thermal fuse in your GE dishwasher. However, if you are unsure or do not feel confident in performing these tasks, it is recommended to seek assistance from a professional appliance repair technician.

Remember, always prioritize safety when working with electrical appliances and disconnect the power supply before attempting any repairs or tests.
