Four Corners Part One - Ice Cream Melts in the Desert

On Saturday May 15, 2021 – I traveled 358-miles from Simi Valley, California to the Fort Beale RV Park in Kingman, Arizona. Towing our fifth wheel trailer across the Mojave Desert took longer than the expected six hours. Once I was set up for the night, I opened the refrigerator in my coach, seeking a cold drink. To my surprise, the refrigerator was dark inside, indicating some form of power failure.

I checked the fuses, circuit breakers and switches in the coach, but the control panel for the fridge remained dark. Since I had packed the unit with two weeks’ worth of frozen and fresh foods, I knew I had a problem. Not wanting to scuttle my trip on the first day, I walked to a nearby Chevron Station and purchased three disposable foam coolers, plus 30-pounds of ice. Back at the coach, I packed ten pounds of ice into the freezer and transferred as much of the fresh food into my coolers as possible. Then it was time to eat some melting ice cream and throw the remainder away.

In the morning, I called a local RV repairman, but he was out of town on another call. He suggested that the printed circuit board (PCB), which is the electronic brains of the unit may have failed. Since I had a non-refundable reservation that night in Flagstaff, Arizona, I could not afford to stay another day in Kingman. On the way out of town, I stopped at the local Wal-Mart, where I purchased two 48-quart red, white and blue Igloo brand ice chests. In the Wal-Mart parking lot, I transferred my fresh food from the leaky foam coolers to my bright new All-American coolers. At $14.85 each, they would do a more efficient job of keeping my food chilled. I put a fresh bag of ice in the non-working freezer and used the previous night’s ice to flood the ice chests.

With nothing more to do in Kingman, I headed 150-miles east on Interstate I-40. My destination was the Kit Carson RV Park in Flagstaff, Arizona. The Kit Carson RV Park declares itself to be the second oldest continuously operating RV Park in the nation. At 6,900 feet elevation, it is always a rustic and cool stopping point during my regional travel. As with most RV Parks, it is best to make your reservations well in advance. Many, including Kit Carson now accept reservations only on a prepaid and non-refundable basis.

Still determined to get my refrigerator operating, I called Buddy’s Welding & RV, which happened to be along my route north the following morning. After looking up my Dometic refrigerator model and serial number, the nice person there said that she had the appropriate PCB to complete my repair. On my way to Monument Valley, Arizona, I stopped at Buddy’s and paid $168 for the Dinosaur Electronics brand aftermarket PCB that was to replace my supposedly defunct OEM model.

After traveling 175-miles to Goulding’s RV Park in Monument Valley, Arizona, I quickly set up for a two-night stay. I then opened the refrigerator access panel on the outside of the coach. Soon, I had the replacement board installed and ready for the final electrical connections. Having carefully marked each wire-lead with a black marking pen, I soon noticed an extra connection wire, without a corresponding terminal on the PCB. It was approaching 4 PM PDT when I called customer service at Dinosaur Electronics Inc. in Lincoln City, Oregon.

After describing my issue to Joe at Dinosaur Electronics, he quickly determined that I had the wrong board. He said it was an easy mistake for the person at Buddy’s to make. In the process of agglomerating Dometic model and serial numbers, a third-party database could not be relied upon for reliable information. There were simply too many combinations of refrigerator models and PCB numbers for the database to handle. Once it was corrupted, there was no way to straighten the database out. Live and learn, I thought. By then, the last of my ice was melting in my coolers. My freezer would soon thaw completely. Standing there in the hot sun, I felt the pangs of bad luck returning.

It was then that Joe said, “Let us see what we can do. Do you have a multi-meter?” “At home, but not here”, I said. “Wait, Joe, my neighbor here had earlier offered to help”. “OK, reinstall your old board, get the multi-meter and call me back”, said Joe. My RV neighbor at Goulding’s was a veteran of the Alcan Highway to Alaska, so of course he had a multi-meter buried somewhere in his huge Class-A motorhome. Once I had the old board reinstalled and the multi-meter in hand, I called Joe back and said I was ready. First, he asked what make and model number multi-meter I had. He then looked up that information on the internet and said, “That is an old analog meter”.

Over the next twenty minutes, we checked all the 12-volt and 120-volt connections that converge inside the refrigerator access panel. After all that, Joe said, “It sounds like you have a bad thermo fuse”. Again, my heart sank at the same rate that my remaining ice was melting. “Do you have wire?”, Joe asked. “I just bought 30-feet of it in Kingman”, I said. “Good. Cut a length of wire and strip it at both ends. Then, get out your electrical kit, find a spade-connector and crimp it on to one end of your wire”. By some good fortune, I had an automotive style electrical kit, complete with spare spade-connectors.

“OK, done”, I said. Luckily, I had a wireless headset for my mobile phone, or I never could have balanced the phone, multi-meter and replacement parts outside of my RV. “Alright, attach the spade connector to the F-5 terminal on the PCB and crimp the other end into the 12-volt terminal block.” After a few more minutes sweating in the afternoon sun, I had the repair completed. “Go inside and see if it lights up”, said Joe. After sprinting inside my rig for the fifth or sixth time, “Still dead”, I reported. “You blew a fuse”, he said. Go to the 12-volt panel in your coach and replace the blown 15-amp fuse”. Luckily, I still had several spare fuses in my kit.

When I plugged the spare fuse into the receptacle, the orange LED on the refrigerator control panel lit up. “You are good to go, for now. The jumper wire is for test purposes only. You need to get it diagnosed and repaired as soon as possible”, said Joe. He had already offered to replace my erroneous Dinosaur Board with the correct model number, so I had him ship that to my next stop, in Durango, Colorado. The replacement cost another $34, but at least I would have the correct spare board. Thanking Joe for his amazing service, I signed off and enjoyed the hum of my refrigerator, as it slowly chilled my frozen food. Above air conditioning and running water, refrigeration in the desert is what makes RVing possible.

After two nights in bucolic Monument Valley, I hooked up and headed northeast to Durango, Colorado, 165-miles away. To me, the refrigerator still seemed like a ticking time-bomb, waiting to go off at any moment. Somehow, the jumper-wire repair held, and my fresh and frozen foods were all chilling in the Dometic unit. Although the frozen meats and fish came close to melting, only one hamburger patty melted a bit and then refroze solid to the bottom of the freezer.

Arriving at United Campgrounds, Durango in the late afternoon I unhooked for three nights in the picturesque Upper Animas River Valley. Almost a decade prior, I had installed a primitive webcam at the RV Park, but it had failed during the recent health crisis. In October 2020, I was so concerned with health protection that I forgot to bring a $25 replacement webcam to Durango. The old Dell computer system whirred away each day, but no images made their way to the internet. Determined to get the webcam operating, I had planned my entire 1,800-mile round-trip with the focus of replacing that webcam.

For those who do not know, the Durango & Silverton Narrow Gauge Railroad first operated in 1882. With a few minor alterations and with some new locomotives from the 1930’s, it still operates today. It is an international tourist attraction that I first rode with my father in 1965. As it was in the 1880s, the railroad is still the economic lifeblood of Durango, Colorado. The webcam is located adjacent to the tracks, within the United Campgrounds RV Park. For years, people from all over the world have relied on the webcam for a glimpse of the trains running through the RV Park. Unless I could repair the system, all that visitors would see was a frozen image from summer 2020.

Borrowing a stepladder from Tim and Sheri Holt, the owners of the iconic RV Park, I swapped out the old Microsoft webcam for an equally old spare that I had brought from home. When I restarted the 20-year-old Dell tower computer, the system booted up and began firing images to the internet ever six seconds. With all the refrigerator electronics issues I had recently experienced, you can imagine how happy I was to see this old electronic marvel spring back to life.

On my second day in Durango, a cold rainstorm, including some hail in the evening, swept through the Upper Animas Valley. Even though it was May 20, the surroundings mountains received fresh snow. I was content to go shopping in Durango for fresh food and to avoid highway traffic. One woman at the City Market declared, “So many people have moved here in the past few years, they don’t even know it can rain here”.

For almost twenty years, the entire Four Corners Region has been in the grip of a long-term drought. It is of a magnitude not seen since the Anasazi, or Pre-Puebloan Indians vacated the region in about 1,200 CE.
