I have a 2004 National Seabreeze and having trouble getting my Atwood 6 gal propane HWH to light. I blew out the fittings and had the circuit board tested and all is well. It 'sparks' but it won't light. The propane is full. Any ideas?

Tink,

Atwood Water Heater Troubleshooting

Hey Tinkman,

I just went trying to keep my 6 gal Atwood alive for the past year or so. I think they make a great unit, but 10-15 years for any water heater is a long time. Check out the easy fixes ......

First step is ALWAYS to break and make all the electrical connections. Real easy to pull off the spade connectors and the wiring harness, then re-attach. Hopefully, you will scrape off some oxidation and be back in business.

Second step would be to check the burner pipe. Adjust the air intake and make sure the burner tube is clear of any obstructions or debris.

Third step, for me, was replacing the unit. Others would say to pull the controller board and replace it. Rather than throw anther $100 into a 15 year old heater and a "maybe" fix, I opted to replace it. A propane only unit can be purchased for under $250.

The removal and installation went really quick ... maybe 2 hours. You re-use your old exterior door, so your paint job or graphics are not affected. I actually bought a replacement unit that was both propane and AC powered. A nice upgrade for a bit more money.

Good luck on your fix.

Here is the service manual for your water heater. See page 21.

When you blew out the fittings did you blow out the orifice as well (the Gas Jet)? I will assume yes.

For this test you will need two things A Multimeter (Voltmeter will do) or test lamp and a feromagnetic metal rod or bar.. Some table knivew work well so should most flat bladed screwdrivers.. NO NEED FOR A SHARP EDGE

With the heater off and cold connect the mter or test lamp to the gas solenoid leads.. Hold the metal bar/tool near (like a quarter inch distant) to the solenoid coil.. have partner turn it on (Gas mode) or do so your self depending on location of controls.

You should see voltage/light and feel the pull of the magnet.
