The fridge in our 2016 179 will no longer work on AC. If I select it, a few seconds later the panel starts beeping. Battery and propane don't have a problem. What should I look at, other than the breaker or GFCI, which I've already checked? I also visually inspected the control panel circuit board and didn't see anything scorched. Maybe a dead heating element?
We have a rally in a couple of weeks and, while we could run off propane or the battery/converter, I'd like to try to get AC working again. TIA. Alan ------------- Alan 2022 R-Pod 196 "RaptoRPod" 2022 Ram 1500 Lone Star 4x4 Three cats |

Alan, If you have checked CBs and fuses, I'm sure you have verified 120 at fridge plug. If that 120 is good, primary suspect is the heating element. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

+1 to what Mike suggests. Check that you're getting both 12V and 120V to the fridge. If that's there, then the next suspect would be the heating element. IDK if both 12V and 120V use the same element or not, but it's possible. if the element checks out, then the next thing would be the control board.

Looks like this is a link to the service manual or one to a very similar fridge. Haven't looked at it in detail but page 39 looks to be the troubleshooting flow chart for AC operation. The most likely culprit is indeed the AC heating element, which is not the same as the DC one. Gives you a resistance value to check, do you have a multimeter. Goes without saying but for sure TURN OFF THE AC power before doing this test. https://www.manualslib.com/manual/1241969/Dometic-Rm-8401.html?page=39#manual ------------- 1994 Chinook Concourse 1995 RV6A Experimental Aircraft 2015 Rpod 179 - sold |

I won't be able to check it until I can pull the Pod out of our storage unit. Since propane and battery are apparently working, I'll probably check it at our next rally, coming up in a couple of weeks. ------------- Alan 2022 R-Pod 196 "RaptoRPod" 2022 Ram 1500 Lone Star 4x4 Three cats |

Let us know when you get chance to look at it. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

I'm having the same issue with my fridge. The electric setting light comes on and beeps. The slide out is supposedly on the same fuse and it works. I'm not sure what a heating element looks like or I would check that. I have always had no trouble plugging it in at the house until now...thoughts? I need to use the fridge for four days... I do have a cooler, but would like to be able to use the ac fridge. ------------- FROGGY |

Until you get it fixed use propane. It works well and is not expensive.

Thank you. I did finally figure it out! I reset the electrical outlet by the bed and surprise, surprise it worked! ------------- FROGGY |

It appears I have a wiring issue. I checked power at the fridge AC outlet (behind the lower vent on the outside) and I’m essentially getting nothing (~0.35 VAC on my Fluke multimeter). I verified that the GFCI breaker was on by plugging in a fan. Does anybody know how the wiring from the GFCI outlet to the fridge outlet is routed in a 179? ------------- Alan 2022 R-Pod 196 "RaptoRPod" 2022 Ram 1500 Lone Star 4x4 Three cats |

Many (most? all?) of the outlets in our RP179 are slaved to the GFCI. Check some of the other outlets to determine if they have power. If not, then there is probably something wrong with the slave side of the GFCI. Otherwise, it may just be a breaker. ------------- bp 2017 R-Pod 179 Hood River 2015 Ford F150 SuperCrew 4WD 3.5L Ecoboost |

The fan is plugged into one of the slave outlets and it’s running fine. Is there a separate breaker between the GFCI and the fridge outlet? ------------- Alan 2022 R-Pod 196 "RaptoRPod" 2022 Ram 1500 Lone Star 4x4 Three cats |

Bum,
I think not. There is a CB labeled so and a resettable GCFI outlet, you should be able to measure 120 at fridge outlet with both engaged. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

One other thing you might check— On our 179, the wiring for the refrig and other thngs in the slide are located in the wood panel below the fridge. Take it off and check all the connections. From that panel, the wiring goes into the bottom of the hassock closest to the refridge. From there it goes through a channel under the floor and over to the main fuse/cb controll unit. Check all of the connections. As the slide moves ina and out, these wires get moved around and it may be a simple loose connection. Hope ths helps Vann ------------- Vann & Laura 2015 RPod 179 https://postimg.cc/0zwKrfB9">

I have a new issue. Last year it work on all setting, 120V, propane and 12V. We went camping last week and the 120V worked fine. But when I push the button for propane, no light, not even the clicking sound. When I push the button for 12V, no light. Does and one had this happen? ------------- Rick and Melanie 2008 Tundra CrewMax 4-Wheel Drive 2015 R-179 Surfer |

Did you bleed the air out of the gas lines? That is often a cause of not lighting. As for the 12vdc, check the fuse. There will be a red led glowing if it's blown. If there's gas, you may want to check and clean the burner. If you don't have screens on the vent openings, little friends can get in during your temperate winter and take up residence. ------------- Never leave footprints behind.
