Troubleshooting RV Appliances | Pesky Problems

Hello all! This month, we’ve acquired questions on numerous RV home equipment. Bear in mind to ship your RVing inquiries to [email protected].

Hello Mark,
We’ve seen a rise of icing on our fridge-cooling fins. It’s the unique Norcold fridge in our 1996 Itasca Dawn. Meals stays chilly at a midrange setting and the freezer appears to maintain issues frozen sufficiently, so there’s nothing to complain about apart from a priority in regards to the icing. We do clear out the fridge and freezer routinely. The icing is going on whereas we’re hooked as much as shore energy and doesn’t appear to be any totally different whether or not it’s set for regular operation or excessive humidity.  We solely run on gasoline sometimes. Questioning if there’s something we ought to be doing in another way.

Hello Phil,
Normally, when an RV fridge begins forming extra frost however nonetheless cools usually, I’d have a look at the door gasket. It doesn’t take a lot of a leak to let humid, heat air into the fridge and that can undoubtedly improve frost manufacturing.

Visually examine the door seal for any tears or apparent issues. Clear each surfaces. Now, shut the door with a greenback invoice inserted between the door seal and the physique of the fridge. You need to be capable of pull it out with some resistance, however in areas the place the seal will not be making, it is going to be very simple to tug out or totally unfastened. Normally, there’s no technique to repair a door seal, you simply have to interchange it. It’s not a really arduous job to do.

Another potentialities: have you ever modified your weight loss plan not too long ago and are loading new meals that have a tendency to hold extra moisture with them? Have you ever not too long ago moved the RV to an space with extra humidity?

I take care of frost build-up in my small Norcold fridge by including a small 12-volt DC electrical fan to blow on the right-hand facet of the coils. That’s the half that will get the coldest, and the circulating air actually reduces frost buildup whereas sustaining very low inside temperatures. The fan could be fed from the 12-volt DC energy supply behind the fridge. For those who use a small muffin fan, it could possibly run repeatedly as a result of these small followers solely draw about 150 mA (Milliampere) of present.

Expensive Mark,
I’ve a Wilderness 27-foot journey trailer.  My downside is the warmth. I don’t know when it’s going to run and when it might resolve to not. We took a visit to Pigeon Forge, Tennessee, final 12 months for Thanksgiving. We turned on the warmth and heard the lighter was attempting to ignite, tick tick ticking, but when it didn’t need to ignite. We have been simply getting chilly air. So we performed with the thermostat and turned it on and off, and also you’d by no means know if it was going to be warmth or simply fan going. I can inform it’s attempting to ignite trigger I hear tick tick, but when it doesn’t need to, it’s simply not reliable, and we wish to camp within the winter from time to time. Any solutions? Somebody mentioned to scrub the igniter, however I don’t even know the place that’s. Somebody talked about it might be propane is low. I simply don’t know, however I would like it reliable.

Hello Sharon,
It’s no enjoyable to have a furnace that you would be able to’t belief! A number of issues may cause the issue you’re seeing. It may be an issue with the propane provide to the furnace or low battery voltage on the furnace, however I believe yours is an igniter downside or a circuit board downside. There are two steel probes contained in the combustion chamber of the furnace {that a} spark jumps throughout to gentle the gasoline burner. That’s the “tick tick” sound you hear. These probes could also be soiled, misaligned, or there could also be an issue with the excessive voltage connection to the furnace igniter board. If in case you have the handbook for the furnace and are helpful with instruments, the igniter probes are comparatively simple to take away and clear. The handbook ought to present you the place they’re positioned contained in the furnace. If cleansing the probes doesn’t assist, the issue could also be in both the furnace management board or presumably the gasoline valve.

Sadly, furnaces actually ought to be repaired solely by of us who perceive the protection facets of working with gasoline home equipment. In case you are unsure what you’re doing to your personal security, have a professional technician diagnose and restore your furnace.

You might have addressed this query earlier than, however a buddy advised us that it’s not good to park our rig and go away every part off, particularly the fridge. He mentioned it’s not good to permit the coolant to settle to the underside of the unit quite than flow into continuously. Our unit works off propane or electrical, and we now have been conserving the camper plugged into the home simply to maintain the fridge working. Truth or fiction?

Hello Sonny and MayLynn,
I’d should forged my vote for “fiction.” Leaving the fridge off when you find yourself not utilizing the RV is not going to adversely have an effect on its lifespan. Working it repeatedly gained’t actually harm it both, so long as it’s stage, however the electrical heating component that operates the fridge when it’s on AC could finally burn out; plus, it takes a number of hundred watts to function. Save your cash: RV fridges are designed to be turned on and off with out inflicting any issues. Simply go away it off, and prop the doorways open in order that it doesn’t scent musty inside. You might have to take away the within 12-volt gentle bulb whether it is nonetheless on when the fridge is turned off and the door is open.

How do I clear out the water heater tank on my 1987 Bounder? 

Hello Linda,
First, be certain that it’s chilly, or a minimum of cool. Flip off the water heater, ensuring that each the gasoline burner and the electrical component (if that’s the case geared up) are off. Then, flip off the water pump, or disconnect the hose from town water inlet. Open a scorching water faucet to launch any strain, go away it open and go exterior. Open the water heater entry panel, and utilizing an acceptable device, take away the water heater drain plug. As soon as the heater has drained, flush the within of the tank via the drain plug by utilizing a water heater flushing device obtainable at any RV elements retailer. The flushing device is a protracted, skinny nozzle that attaches to your backyard hose and matches into the water heater drain opening. One standard model is named a tank saver.

As soon as it’s all flushed out, exchange the drain plug and switch the water again on. Let the water heater fill till water runs from all open scorching water taps earlier than turning the warmth again on. It’s greatest to do that a minimum of yearly.

Hello Mark,
We’re staying at an RV park in Tillamook, Oregon. We now have a 30-amp connection.

The primary morning after we arrived, it was about 45 levels. I turned on our electrical fire and began my microwave to warmth my tea water. I normally set it at 2min 30 secs. When the water was carried out, it was barely heat. Then I seen that the heater wasn’t as heat as traditional. I believed that the microwave was on the fritz. I checked the facility on the pole. I seen that the three lights on the surge protector weren’t all inexperienced. The primary gentle was purple however the others have been inexperienced. The checklist of faults mentioned it was the L1 and L2 and impartial have been reversed. I advised the park of the issue, they usually despatched an electrician to treatment the issue. It was superb for a day. Subsequent morning similar problem. Nevertheless it was repaired. I believe it might be a provide problem on the park. There are about 65 different trailers right here. Simply searching for your ideas on this problem.

Hello Jeff,
Is your rig 50 amps and have been you utilizing a 30- to 50-amp adapter on the time? If that’s the case, these may cause some surge protectors to report a wiring downside, and it’s not normally an issue to function that method.

Additionally, in case you are used to having a 50-amp hookup, working on 30 amps requires load managing. Within the instance you offered, working an electrical heater (fire) and the microwave on the similar time together with the fridge and battery charging may push you over 30 amps. Low voltage can also be a chance: if the park’s system is overloaded and the voltage drops, it may make issues just like the microwave warmth slower.

If the issue recurs on the subsequent place you keep, then it’s one thing that must be appeared into. I believe, such as you, that it’s an influence problem on the park, and as such, shouldn’t comply with you down the highway. 😊
