Manual For Troubleshooting An Atwood Water Heater

Due to repeated usage and inadequate maintenance, your Atwood water heater may eventually begin to malfunction.

These will cause a number of problems, including the main burner not starting or staying lit, a dead pilot, no hot water, smoking or soothing, no gas, no power or gas operating, no spark on electrodes, and others.

In this chapter, we will discuss the causes of various heating issues and their straightforward fixes, which also apply to Atwood gc10a-4e troubleshooting.

Here is a tutorial for troubleshooting an Atwood water heater:

#1. Heater Is Gas-Free

Without gas supply, your Atwood water heater may shut out.

Here are some possible causes of this problem.

You may read our tutorial on how to handle the Atwood furnace ignition lockout fault if you’re having lockout problems.

  • A problem with the gas valve’s solenoids
  • Blocked main burner tube or orifice
  • E.C.O., solenoid valve, or wiring harness loose or damaged wire connections


Follow these instructions to resolve such problems:

  • Put a new solenoid valve in place of the broken one.
  • An air compressor or an attachment brush may be used to clean the orifice and the burner tube.
  • On the E.C.O., solenoid valve, and wiring harness, make secure wire connections.

#2. The Atwood Water Heater Will Not Stay Lit And Keeps Turning Off

Your RV water heater may sometimes start up and then shut off.

The following causes contribute to this problem with switching off.

  • Defective thermocouple
  • Incorrect control board
  • Faulty or problematic pilot assembly
  • A bad gas supply or defective gas valve


Continue with the next few steps to relight your water heater.

  • Change the old thermocouple with a new one.
  • Make a new pilot assembly
  • Replace the gas valve and make sure there is adequate gas flow.
  • In addition, if the control board is broken, replace it.

Note: Be aware that changing the gas valve will take a lot of work, and electrical expertise is recommended.

To discover how to replace the gas valve, see a video instructional.

  • Porcelain electrodes with loose wire connections
  • Deposit matter on the electrodes
  • Circuit board fault


Do this to address the problems:

  • The electrodes to the primary burner and fasten them.
  • Switch out the electrodes
  • Deposits on the electrodes should be removed.
  • Circuit board replacement

#5. Uneven Flame or Sooting on the Burner

The accumulation of soot occurs for the reasons listed below:

  • A little or insufficient gas pressure
  • Defective or imperfect main burner alignment
  • Burner orifice obstruction
  • Poor access to gas
  • Blockages occur in U-tube
  • Ineffective air adjustment


Let’s now go through the procedures for cleaning soot buildup from your RV water heater.

  • To boost the gas pressure, place the intake pressure at least 11′′ W.C. with two or more gas appliances operating.
  • Perfectly line the main burner and adjust the valve.
  • Use an air compressor or a brush to clean the burner orifice. Make careful while cleaning that you don’t widen the orifice.
  • Put a new gas supply in place of the current one.
  • Your main burner’s air shutter should be adjusted so that it always stays 1/4 open.

#6. Pilot Defect

The following are likely causes if you find your heater’s pilot is out and your RV water heater isn’t working:

  • The gas pressure wasn’t adequately adjusted by you.
  • Your water’s thermocouple and gas control magnet may not be strong enough.
  • You don’t correctly adjust the air.
  • The pilot flame of the water heater becomes blocked.
  • Your heater’s “U” tube might get clogged.


  • Make careful to operate two or more appliances while maintaining a pressure of at least 11 W.C.
  • Replace both the gas control magnet and the thermocouple.
  • Open the air shutter by 1/4. (approximately).
  • If necessary, replace or clean the pilot light on the water heater.
  • Remove the block and clean the U tube.

#7. Pilot Failure After Depressing the Button or Knob

After releasing the heater knob or button, the pilot may sometimes go out.

The following are the root reasons of this issue:

  • Not hot enough is the thermocouple.
  • Unstable thermocouple
  • faulty gas control
  • faulty thermocouple


  • Hold the thermocouple for 30 seconds before releasing it.
  • Enough tighten the bond.
  • Switch out the gas control.
  • Switch out the thermocouple.

#8. Main Burner of the Heater Is Not Lighting

The following are causes if your heater’s pilot light is on but the burner won’t ignite:

  • The primary burner orifice might get obstructed or clogged.
  • Faulty gas control.
  • Dirt forms a seal in the “U” tube.
  • The primary burner has a block.


  • If necessary, clean the orifice or replace it.
  • Switch to a new gas control panel to replace the damaged one.
  • sanitize the U tube.
  • Clear the clog in the primary burner.

#9. Water With Insufficient Temperature

The following are the primary causes of the inadequate water temperature:

  • It’s possible that the temperature selection won’t stay put.
  • The bypass levers are positioned incorrectly.
  • Part of the burner becomes blocked.
  • Faulty air adjustment


  • The temperature option should be moved.
  • Ideally place the bypass levers
  • Remove the burner’s obstruction
  • Set the air shutter to be about 1/4 open.
