The water heater would not ignite In the gas mode, on our recently purchased 179. DSI light was staying on. Checked the flume, and the reset switches, they were fine. Checked the ignition control board, which was mounted to the water heater by double sided tape and a cable tie. Discovered the Q3 contacts located on the back of the circuit board covered by the double sided tape to be burned out. This is a Suburban Water Heater SW6DE, replacement board $100+ (Made in China) 90 day warranty. We purchased a new Dinosaur Electric, UIB S (small) $88+ (Made in USA) 3 year warranty. Working great, easy fix. However would recommend purchasing a cover/case as old Suburban case will not fit. It is slightly bigger. The UIB S also has a 5 amp fuse built in, along with some LED lights and some test ports. It gets really good reviews Hopes this helps with any water heater ignition problems ------------- 2018 179 2012 NISSAN XTERRA (retired 12/19) 2019 RAM 1500 WARLOCK (new) A.R.E.

Thank you for this information. I have not experienced any problems with our water heater, but it is good to file the information for future reference if needed.

Quick water heater question,
I'm at Shenandoah national Park at 3000' my water heater fires for 6 seconds and then the flame turns off this started happening yesterday, it worked fine the first two days. Propane tanks are full and everything else propane related works fine. Any thoughts? ------------- http://www.rpod-owners.com/forum_posts.asp?TID=9426&title=slopod-180-mods-johnsue - SLOPODMODS John&Sue,SLO,CA 2016 180 HRE, 2013 F150 Eco Boost

You are obviously getting gas and an ignition spark if it fires for 6 seconds. Sounds like maybe a blockage? and it can't keep up with enough propane fast enough? ------------- 2017.5 Rp-172 2020 R-pod 195 2015 Frontier sv 4.0L 6cyl I'll be rpodding |

Its probably the flame probe electrode not contacting the flame properly. If it doesn't make contact the control board will think that the flame has gone out and will shut off the propane for safety. The probe can be adjusted. Here is a link to the service manual. Troubleshooting guides are around page 19. http://waterheatertimer.org/pdf/Suburban_Water_Heater_Service_Manual.pdf - http://waterheatertimer.org/pdf/Suburban_Water_Heater_Service_Manual.pdf ------------- 1994 Chinook Concourse 1995 RV6A Experimental Aircraft 2015 Rpod 179 - sold |

You might want to check for a spider web in the burner tube that also could be a contributor. ------------- Jay 179/2019 |

or a wasp nest. I put screens on all openings to prevent them from getting in and building nests.

Thanks for all the ideas to check! The burner blows full force for the first six seconds and then goes out oh, it did this three times. I'm thinking it must be the flame sensor. I took it apart made sure the Gap was correct in position properly, and no change
Thanks MJ for the manual going to take a hard look at it tomorrow. Real spotty cell service up here. ------------- http://www.rpod-owners.com/forum_posts.asp?TID=9426&title=slopod-180-mods-johnsue - SLOPODMODS John&Sue,SLO,CA 2016 180 HRE, 2013 F150 Eco Boost

Kahunp37,
Still noodling the hot water heater, it's the same model as yours. is the control panel behind the small oval black case below the ignition tube near the gas valve? And now won't light at all, there's no spark, but gas does flow. I can light it with a lighter though but it still goes off after five or six seconds. Fortunately I could just fire it with the generator on electric to get hot water from my wife's nightly shower. As I said before the stove is fine the furnace works fine the refrigerator on propane works fine so it must a problem in the unit somehow. Thanks John ------------- http://www.rpod-owners.com/forum_posts.asp?TID=9426&title=slopod-180-mods-johnsue - SLOPODMODS John&Sue,SLO,CA 2016 180 HRE, 2013 F150 Eco Boost

Sorry for the delay. The black box you referred to, contains the reset switches, for both the 120 volt (left) and 12 volt (right) systems. There are several YouTube videos on these items. I don’t recommend unsafely lighting it from the flume. Let me know if this helps. ------------- 2018 179 2012 NISSAN XTERRA (retired 12/19) 2019 RAM 1500 WARLOCK (new) A.R.E.

Kahonu37,
Thanks for the input, I found the reset switches they are above the gas valve, a big square rubber cover with two resets on it. the one I was referring to is under the gas valve to the right. it's an oval cover down near the bottom next to the electric switch. we're heading back home in the morning. I plan to take a hard look at it when I get back. thanks for letting me know where the sensor is, I'll let you know how it goes, thanks again. ------------- http://www.rpod-owners.com/forum_posts.asp?TID=9426&title=slopod-180-mods-johnsue - SLOPODMODS John&Sue,SLO,CA 2016 180 HRE, 2013 F150 Eco Boost
