Electrical Issues

Electrical issues are a frequent cause of the reset light coming on. Loose connections can disrupt the power supply. Faulty wiring can also cause irregular power flow. Check for any damaged wires. Ensure all connections are tight and secure.

A malfunctioning thermostat can also trigger the reset light. If the thermostat can’t regulate the temperature, it may cause the heater to overheat. This activates the reset light. You might need to replace a faulty thermostat. Make sure the thermostat is set to the correct temperature.

Initial Checks

Having your RV water heater reset light constantly coming on can be frustrating. Before you panic, performing a few initial checks can help you identify the problem. Let’s dive into the key areas to inspect.

Power Supply

First, ensure that your RV is receiving a steady power supply. Check if your power cord is properly connected and not damaged. A faulty power supply can cause the water heater to malfunction.

Here are some quick checks for the power supply:

• Inspect the power cord for any visible damage.
• Ensure the power plug is securely connected.
• Verify that the circuit breaker has not tripped.

Reset Button

The reset button is a crucial component of your RV water heater. It can trip due to various reasons, such as overheating or a power surge.

Here’s how to check the reset button:

1. Locate the reset button on your water heater.
2. Press the button firmly to reset the system.
3. Observe if the reset light turns off.

If the light stays on, there might be an underlying issue. Regular maintenance can help prevent frequent reset issues.

Inspecting The Thermostat

When your RV water heater reset light keeps coming on, the thermostat might be the issue. The thermostat controls the water heater temperature. If it malfunctions, it can trigger the reset light. Let’s explore how to inspect the thermostat properly.

Location And Access

First, find the thermostat. It’s usually located behind a small access panel on the water heater. Remove the screws holding the panel in place. Be careful not to damage any wires.

Once the panel is off, you should see the thermostat. It’s a small device with a dial or a set of buttons. Ensure the power to the water heater is off before touching anything inside.

Adjustment And Calibration

Now, check the thermostat’s settings. Use a screwdriver to adjust the temperature. Turn the dial slightly and see if the reset light stops coming on.

If adjusting doesn’t work, the thermostat might need calibration. To calibrate, follow the manufacturer’s instructions. Usually, it involves turning the dial to a specific setting and then back to the desired temperature.

After calibrating, test the water heater. Turn the power back on and observe if the reset light stays off. If the problem persists, the thermostat might need replacement.
