Temperature Control and Thermostat Issues

Atwood Water Heater Thermostat Troubleshooting

Understanding temperature control in Atwood water heaters is key for good maintenance. Most 6-gallon models are set to 140°F by default. This can sometimes lead to heating issues.

Thermostat problems can show up in different ways. You might find water too hot or not hot enough. This suggests a problem with the temperature control system.

  • Preset temperature limitation at 140°F
  • Potential thermostat malfunction
  • Solenoid valve control problems
  • Emergency Cut Off (ECO) sensor failures

To fix temperature issues with your Atwood heater, follow some diagnostic steps. First, check the thermostat connections. Then, look at the emergency shutoff mechanisms.

SymptomPotential CauseRecommended Action
Water too hotFaulty thermostatReplace thermostat kit
No hot waterECO sensor failureCheck electrical connections
Inconsistent temperatureSolenoid valve issueInspect and potentially replace valve

Consider the optional Atwood adjustable thermostat (part #93105) for better control. Replacing it is easy and can be done in about 20 minutes. Just make sure to follow safety guidelines.

Most Atwood water heater repairs can be done by yourself. This includes fixing temperature control issues. So, if you’re confident in your DIY skills, you can tackle these repairs yourself.

Water Pressure and Leakage Problems

When your heater isn’t working right, water heater leaks can be a big problem for RV owners. It’s important to know why these leaks happen. This helps keep your Atwood 6-gallon water heater working well and avoids expensive fixes.

Identifying Leak Sources

Leaks can come from different places. Here are the main spots to check:

  • Connection points around valves
  • Pressure relief valve openings
  • Tank body seams
  • Pipe connections

Pressure Relief Valve Issues

The pressure relief valve is key to stopping too much pressure. If it fails, it can cause leaks and dangerous situations.

SymptomPotential CauseRecommended Action
Constant drippingValve malfunctionReplace pressure relief valve
Water dischargeExcessive system pressureCheck system pressure settings

Tank Corrosion Signs

Even with a protective lining, Atwood water heaters can corrode. Look out for these signs:

  1. Rust-colored water
  2. Visible rust spots on tank exterior
  3. Recurring leaks near tank bottom
  4. Unusual odors in hot water

Regular checks and upkeep can stop pilot light problems and find water heater issues early. Being proactive keeps your RV’s water heating system running smoothly and efficiently.

Electrical System Diagnostics

Electrical system problems can really hurt your Atwood water heater’s performance. It’s key to know how to find these issues to keep your heater working well and avoid big problems.

When you’re trying to fix heater temperature issues, start by checking the electrical parts. Make sure they’re working right.
