Checking an Atwood ignition fault
We first inspect the wire connections and ground. Then we check that the electrode gap is 1/8 inch and that the probes are clean and positioned in the gas-flow path. These checks help us assess the existing ignition assembly before moving to replacement.
Testing propane pressure under load
We check propane pressure with two or more gas appliances running. Atwood specifies at least 11 inches water column under load. Testing the water heater alone does not establish whether the supply meets that requirement while other gas appliances are operating.
Burner cleaning and electrode work
We use a brush to clean the main burner tube. For electrode replacement, we use a spark electrode assembly. Burner cleaning and electrode replacement are separate tasks; the ignition inspection guides which work we recommend.
Budgeting for a water-heater swap
Estimated labor for a basic RV tank water-heater swap is $200 to $400. That range is for swap labor, not a repair package covering diagnosis, burner cleaning and electrode replacement. It also does not provide a price for the replacement heater or parts.
Harlingen permit requirements
Contractors performing permitted work must be licensed and registered with the city. Those residential requirements do not, by themselves, establish whether a particular RV water-heater job requires a city permit.

Depending on what we find, that can mean:
- On a Suburban unit, remove the anode with a 1-1/16-inch socket and replace it when consumption or weight loss exceeds 75%; apply potable-water-approved thread sealant to the replacement rod’s threads. [Suburban manual]
- If the tank is corroded, replace the water-heater unit; Mobile RV Pro states that tank corrosion is not repairable. [Mobile RV Pro]
