RV Refrigerator Repair in San Marcos, TX

RV Refrigerator Repair · San Marcos, TX

For the RV fridge that quit cooling or lost power

RV refrigerator repair starts with what the fridge is doing. Maybe it quit cooling, or it cools on electric but not on propane. Maybe the control panel went dark, or the fridge smells like ammonia. We find the cause, then put the quote for the repair in writing.

We work on absorption fridges that run on propane and electric, and on 12-volt compressor fridges. The service call comes to your RV at an RV park, a campground, a storage lot or a driveway. You can also bring the RV to our San Marcos shop. Our mobile RV repair around San Marcos reaches about 50 miles, to the edges of Austin and San Antonio.

What We Handle

  • Fridges that stopped cooling on every power source
  • Fridges that cool on electric but not on propane, or the reverse
  • Heating elements, fuses, burners and flues
  • Loose power wires and dead control panels
  • Ammonia leaks and failed cooling units
  • Absorption fridges and 12-volt compressor fridges
  • RV fridge replacement when a unit is done
  • Service at your campsite or at our San Marcos shop

Why did my RV fridge stop cooling?

An absorption fridge makes cold from heat, which comes from a propane flame or an electric heating element. One fridge maker's service manual notes the design has no mechanical pump or compressor. Liquid ammonia runs through the cooling coils by gravity. That is why a parked RV has to sit close to level.

When the fridge is warm on every power source, look at what both sources share. That manual's troubleshooting list covers the venting, the level, the door seals and the temperature sensor before the cooling unit. A dollar bill shut in the door should drag as you pull it out. If it slides out easily, that part of the seal leaks.

The same manual says the controls need steady 12-volt power, even when the fridge runs on propane or electric. They work down to 9.6 volts, so a run-down battery can shut the fridge off. A loose wire can make it act up, too. Battery and converter trouble falls under RV electrical and generator repair.

RV fridge repair in the San Marcos summer heat

An absorption fridge pulls heat from the food compartment and sends it out through the vents behind it. The same service manual says hotter outside air means hotter air around the cooling unit. A fridge that warms up as the afternoon heats up points at poor venting or a weak cooling unit.

Summer in San Marcos puts that to the test. NOAA's 1991 to 2020 climate normals put the average August high at about 97 degrees. July and August each average more than 28 days at 90 degrees or hotter. A fridge that keeps up in April can fall behind in August.

We come to the RV along the I-35 corridor and out into the Hill Country. At the RV, we check the vents for bird and insect nests and anything else that blocks the air. Then we run the fridge on each power source to find the cause.

RV fridge replacement when the cooling unit fails

The cooling unit is the sealed set of coils on the back of an absorption fridge. It holds ammonia, hydrogen, water and a rust inhibitor under pressure. A leak outside the cabinet can leave a yellow deposit where the ammonia escapes. One maker's service manual recommends no repairs on a failed cooling unit, only a new one.

Replacement means a new cooling unit on the old fridge, or a whole new fridge. Some owners switch to a 12-volt compressor fridge, which runs off the house batteries. One 12-volt fridge manual says a low battery makes it shut the compressor off to protect itself. So the batteries and the charging have to keep up.

The written quote spells out the replacement before any work starts. Once you say yes, we order what the job needs and set a time to install it.

FAQ

RV Refrigerator Repair Questions, Answered

Common questions about rv refrigerator repair around San Marcos and the Hill Country. If yours is not here, call or text and ask.

Call (512) 850-7257

Why does my RV fridge work on electric but not on propane?
The two power sources heat the cooling unit with different parts. On propane, one maker's service manual points at the gas supply, the igniter, the burner and the flue. On electric, it points at the power, the fuse, the heating element and the control board. If the gas supply is the trouble, RV propane system service covers the regulator and the lines.
What does an ammonia smell from my RV fridge mean?
It can mean the cooling unit is leaking. The owner's manual for one fridge says to switch it off at the control panel and keep its doors shut. Then open the RV's windows and doors, and leave the RV. Call or text (512) 850-7257 once you are outside.
Does my RV have to be level for the fridge to work?
An absorption fridge does, whenever the RV is parked for several hours or more. One maker's manual warns that running noticeably out of level can cost you the cooling. Level enough to live in, with no slope you notice in the floor or walls, is the target. On the road, the rocking of the RV keeps the ammonia from pooling.
How much does RV refrigerator repair cost?
The price turns on the fault and the parts it needs. A loose wire is a small fix, and a failed cooling unit means a replacement. The service call covers the diagnosis and the trip within 50 miles of San Marcos. After the diagnosis, we put the quote for the repair in writing.
How long does an RV fridge take to get cold?
An absorption fridge takes a while. One maker's service manual says a first start can take up to four hours. Let the fridge get cold before you load food, and let hot food cool to room temperature first.
Will insurance or a service contract pay for my fridge repair?
That depends on your policy or your contract, and the approval decision is theirs. We diagnose the fridge and send the write-up in for approval. If the claim is approved, you pay your deductible and we take care of the rest. Each step is laid out on our RV warranty and insurance repairs page.

Josh replaced the a/c and heater control board in my travel trailer he did an awesome job I highly recommend him

Dustin Wied8 months ago · Google review

We discovered just 4 days before our Thanksgiving trip that our RV slide-out wasn’t working. We contacted Josh, and he came out the very same day to diagnose the issue. He quickly ordered the necessary parts and managed to get everything repaired in time for our trip. Josh was professional, efficient, and highly communicative throughout the entire process, keeping us informed every step of the way. His pricing is very reasonable, and we truly appreciate the extra effort he put in to ensure we were able to leave on time. Highly recommend his RV repair services!

Josh and his team are amazing. He replaced my roof on my wildcat 5th wheel. And once it rained he returned twice to assess any leaks and concerns. He’s my repair guy now! Thank you Josh!!!!
