The following video demonstrates how to adjust the airflow: 

07. Suburban RV Water Heater Water Too Hot

Your Suburban RV water heater will supply too hot water for the following reasons:

  • High-temperature setting
  • Loose thermostat
  • Incorrect orifice size
  • Improper gas pressure
  • Faulty thermostat

How To Fix:

Here I’m providing some easy and simple steps to prevent your water heater from overheating.

Step 1: The first thing you need to look at is the water heater’s temperature setting. If you have a pilot ignition system water heater, you should find a temperature adjustment dial as shown in the picture below.

suburban rv water heater temperature asjustment dial

If the temperature is set too high, it will cause the water to get too hot. To lower the temperature, turn the dial clockwise until you reach the desired temperature level.

However, for water heaters without a pilot ignition system, there is typically no temperature adjustment dial available. They’re preset at the 120°F setting recommended.

Step 2: Now, check the thermostat placement. The water heater will make the water too hot if the thermostat is not properly secured to the tank.

To secure the thermostat:

  • Turn off the water heater and allow it to cool down.
  • Remove the cover from the water heater and locate the thermostat.
  • Try to wiggle the thermostat and check for any free-play.
  • If there’s any free play, secure the thermostat properly. If you don’t know how to do that, contact a professional.
  • Reinstall the cover and turn the water heater back on to check if the problem is resolved.

Still getting too hot water? Follow the next step.

Step 3: If the orifice size is incorrect, it can cause the water to become too hot.

The orifice is responsible for controlling the flow of gas to the burner, and if it is too small or too large, it can affect the flame size and temperature of the water.

So, make sure you’re using the correct sized orifice. You’ll get the orifice size on your user manual. If it doesn’t match the manufacturer’s recommended size, replace the orifice.

To replace the orifice:

  • Turn off the water heater and allow it to cool down.
  • Locate the orifice at the base of the water heater and use a wrench to remove it.
  • Check the size of the orifice and compare it to the manufacturer’s specifications. If it is too small, replace it with the correct size.

Step 4: If the orifice issue is fixed and the problem still persists, you need to check the gas pressure.

The gas pressure is also responsible for the temperature of the water. If it’s too high or too low, it can also affect the flame size and temperature.

  • Check the gas pressure and ensure that it is set to 11 WC inches to 14 WC inches. If the pressure isn’t within this range, call a technician to fix the issue.
  • Reinstall the orifice and turn the water heater back on to check if the problem is resolved.

Step 5: If none of the above methods fix the overheating issue, the thermostat could be the culprit.

A thermostat failure can also cause the water to become too hot if it can’t control the temperature properly.

To diagnose the thermostat for the water being too hot:

  • Check that both 120V switches are turned on. If the primary switch is not lit, check the circuit breaker or connection on the back of the light switch.
  • The thermostat controls the heating element and stops it when the water is hot enough. The temperature limit is 130 degrees F (+/- 5 degrees F). If the thermostat fails, the water temperature can keep rising.
  • If the water temperature gets too high, a safety switch called a Hi-Limit or Electric Cut Off (ECO) will open the electrical circuit causing no power to the element and cutting off power to it.
  • Press both reset buttons on the back of the water heater.

If pressing the reset buttons restores operation, it means the Hi-Limit/ECO switch had cut off power because the thermostat failed to stop the heating element.

If the problem persists, it could be a faulty thermostat, which needs to be replaced.

08. Suburban Rv Water Heater Bad Smell

A bad smell coming from the Suburban RV water heater is usually caused by chlorination of the water system. This occurs due to the reaction between chlorine and certain organic compounds present in the water, creating volatile gases that emit a foul scent.

How To Fix:

To eliminate the bad smell from your Suburban RV water heater, you need to flush the system following these simple steps:

Step 1: Measure out about six (6) ounces of common household liquid bleach per 10 gallons of water in the tank.

Step 2: Add the bleach to the water tank and turn on the water pump to let the chlorinated water flow through the system.

Step 3: Open each faucet one at a time and run the water until you smell the chlorine.

Step 4: Let the water sit for a few days to allow the chlorine to disinfect the water system.

Step 5: Flush the system with fresh water several times to remove the chlorine smell.

Step 6: To prevent future sulfur smells, consider installing a filtering system that removes chlorine and other contaminants.

Step 7: If the bad smell persists, repeat the process above and replace the anode rod if necessary.

Note: Make sure to handle the bleach carefully and avoid contact with skin or eyes.
