What is a Thermal Fuse and How Does it Work?
A thermal fuse is a small, one-time-use device that acts as a safety switch. It contains a thin metal strip that melts and breaks the circuit when the temperature reaches a predetermined level. This prevents excessive heat buildup that could damage the dishwasher or cause a fire.
Signs of a Blown Thermal Fuse
If your Frigidaire dishwasher is not heating properly or has stopped working, a blown thermal fuse may be the culprit. Other signs include:
- Dishwasher not starting
- Dishes not getting clean
- Dishwasher making unusual noises
- Burning smell from the dishwasher
How to Replace a Thermal Fuse in a Frigidaire Dishwasher
Replacing a blown thermal fuse is a relatively simple task that can be performed by most homeowners. Follow these steps:
1. Unplug the dishwasher.
2. Locate the thermal fuse. It is usually found near the heating element or control board.
3. Disconnect the wires from the thermal fuse.
4. Remove the old thermal fuse by unscrewing or pulling it out.
5. Install the new thermal fuse and reconnect the wires.
6. Plug in the dishwasher and test it.
Causes of Blown Thermal Fuses
Several factors can cause a thermal fuse to blow, including:
- Overheating due to clogged filters or spray arms
- Malfunctioning heating element
- Faulty control board
- Power surges
