- Premium Choice: Suburban 161154 Wall Thermostat – Heat Only – White
When an RV thermostat fails, the whole coach feels it. The furnace refuses to fire on a cold morning, or the roof air conditioner runs all afternoon without a clear way to tell it when to stop. Unlike a house thermostat, an RV unit is tied to a particular brand of furnace and air conditioner, which is why the shopping question is rarely “which one is best” and almost always “which one matches what I have”.
This guide is for owners replacing a dead wall unit, upgrading an old analog dial, or adding smarter control to a travel trailer or motorhome. Whether the coach is a small pull-behind or a large Class A, the wall unit is a small part that controls a lot of comfort. Plan around three decisions: heat only versus heat and cool, analog versus digital, and whether the control must pair with a specific Dometic or Coleman system. The eight thermostats below are judged from their listed part numbers and features, and the advice holds into 2026 for most common coach layouts.

How to Choose
Start with the part number on your old unit
Most listings are built around specific replacement numbers, such as 3106995.032, 83303362, or 7330F3852. Peel off the old faceplate, read the number, and match it to the title. A thermostat that fits electrically but names a different system may still work, but you are guessing, and wiring mistakes can blow a fuse or leave a function dead. Take a photo of the wires before removal and label each terminal, since colors can fade or differ from one build year to the next.
Heat only, cool only, or both
A furnace-only wall unit is correct when the air conditioner has its own separate control. A heat/cool model replaces a single dial that handles both functions. Some coaches pair a furnace control on one wall with an air conditioner control elsewhere, so identify how many controls you actually have before buying. Check your coach: if the roof air has its own switch or box, a heat-only unit like the Suburban or the White-Rodgers may be the right fit, while Coleman Mach and Dometic CT systems expect a combined unit.
Analog dial or digital display
Analog models are plain and easy to read, with fewer parts to fail. Digital models show temperature numerically and often offer tighter control. Programmable units go further, letting you set schedules and, in one case, use WiFi and Bluetooth. If you boondock and watch battery draw, simplicity may outweigh features. A wireless unit adds convenience, but it also adds another thing to configure, and an analog dial keeps working when phones and apps do not.
What to ignore and where budget models cut corners
Ignore generic words like “upgrade” or “premium” without a matching part number. Budget replacements may cut corners on display quality, terminal strength, or wiring documentation, so favor listings that name compatible originals and voltage, such as the 12 VDC mention on the Dometic-style analog unit. Be wary of listings that say “fits many models” without naming any.
The 8 Best Options
Dometic-Style Analog Thermostat 3106995.032
An analog replacement for the Dometic part 3106995.032, described as cool only with furnace control and operating on 12 VDC in white. It suits an owner restoring a classic wall dial in an older trailer, where the original control wore out but the furnace and air conditioner are still healthy.
- Strength: a straightforward dial with a named Dometic part number.
- Strength: 12 VDC is clearly stated.
- Trade-off: no digital display or programming.
Skip it if you want precise temperature readouts, schedules, or any digital display on the wall.
83303862 Digital Thermostat for Coleman
This digital heat/cool replacement lists several Coleman part numbers it supersedes, including 83303362 and a group of 8330-series numbers (336, 337, 338, 339, 368, 386). The long compatibility list is its main strength, because owners who find any of those numbers on the old faceplate can recognize a match without hunting through catalogs.
- Strength: broad Coleman compatibility spelled out in the title.
- Strength: digital heat/cool control in one wall unit.
- Trade-off: it targets Coleman systems and is not a universal fit.
Skip it if your coach uses Dometic or Suburban controls, or if the number on your old unit is not in the list.
Suburban 161154 Wall Thermostat
A heat-only wall thermostat in white from a recognized furnace brand. It is the answer for coaches where the furnace has its own wall control and the air conditioner is handled separately.
- Strength: matched to a brand-name RV furnace maker.
- Strength: simple, single-purpose control with no extra menus to learn.
- Trade-off: it handles heat only, with no cooling function.
Skip it if you need one device for heating and air conditioning, since the air conditioner would then need its own separate control.
Upgrade 83303862 for Coleman Mach
This digital heat/cool wall thermostat replaces the Coleman Mach 83303362 and is described as fitting the Micro Air RV thermostat as well. It also lists 8330-337 and 8330-368 compatibility, which gives owners of those older numbers a path to a digital display without changing the rest of the system.
- Strength: heat/cool control for a Coleman Mach system.
- Strength: the Micro Air tie-in widens its use beyond Coleman alone.
- Trade-off: it overlaps heavily with the other 83303862 listing, so choose by exact part number.
Skip it if your coach is not Coleman Mach based, or if you would rather buy one of the other listings that names your exact number.
Dometic Standard CT Single Zone Thermostat
A black, standard single zone control from Dometic, meant for coaches with a Dometic CT system. It is the like-for-like choice for owners who want the original style back and who would rather not learn a new interface after a long day of driving.
- Strength: brand-matched to Dometic single zone setups.
- Strength: plain, familiar controls.
- Trade-off: the title lists no smart or programmable features.
Skip it if you want schedules or a phone app, since those features are not part of this standard control.
MICRO-AIR EasyTouch Digital RV Thermostat 351
The most feature-rich option in the group: programmable, with WiFi and Bluetooth, black finish, and compatibility with Dometic CT single zone systems. It is aimed at owners who want remote control, such as full-timers who leave pets in the coach or travelers who like the cabin cool by the time they return.
- Strength: WiFi and Bluetooth bring phone-based control.
- Strength: programmable scheduling for heating and cooling.
- Trade-off: more features mean more setup than a basic dial.
Skip it if you prefer a simple wall dial with no wireless features, or if you do not want another device that depends on a phone.
White-Rodgers Emerson M30 Heat-Only Thermostat
A white, heat-only unit from a long-established thermostat maker. The title does not mention RVs, so it is best read as a basic furnace control, and a buyer should confirm voltage and wiring before assuming it will work in a coach.
- Strength: simple single-function operation.
- Strength: recognized brand name.
- Trade-off: no cooling and no RV-specific compatibility list.
Skip it if you need a part guaranteed to match a specific RV system, because the title offers no coach compatibility list.
7330F3852 RV Thermostat for Coleman Mach
A heat/cool replacement for the Coleman Mach 7330F3852, described as a single-stage heating and cooling control for air conditioner parts. It suits owners with that exact number on the old unit, and the single-stage wording tells you it is meant for a conventional furnace and air conditioner pairing rather than anything elaborate.
- Strength: numbered to a specific Coleman Mach part.
- Strength: handles both heating and cooling.
- Trade-off: single-stage only, with no mention of multi-stage control.
Skip it if your thermostat carries a different Coleman number, such as the 8330 series covered by other listings.
Which One Fits Your Situation
A Dometic CT system with a failed wall unit
The Dometic Standard CT Single Zone is the like-for-like replacement, while the Micro-Air EasyTouch 351 is the upgrade for anyone wanting app control.
A Coleman Mach coach
Match the number first. The 83303862 listings suit owners of 8330-series units, and the 7330F3852 suits the 7330 family. If your old unit carries one of the numbers in the long Coleman list, the first 83303862 listing is the more explicit match, while the Micro Air tie-in on the upgrade version appeals to owners already planning a smarter setup later.
A furnace-only wall control
The Suburban 161154 is the natural pick for a Suburban furnace, with the White-Rodgers M30 as a basic alternative if you can confirm fit. In both cases, verify that your furnace expects a heat-only wall unit and that cooling is handled elsewhere.
A vintage analog setup
The Dometic-style analog 3106995.032 keeps the familiar dial, which suits owners who prefer simple, rugged operation. It also makes sense for a seasonal camper who uses the trailer a few weekends a year and has no interest in menus, schedules, or firmware.
Common Mistakes
- Ordering by color or looks without checking the old part number.
- Buying a heat-only thermostat for a coach that needs combined control.
- Skipping the power shutoff before swapping wires, which risks a blown fuse or a shorted terminal inside the wall plate.
- Assuming a household thermostat will work with RV low-voltage systems.
- Choosing a feature-rich model without confirming it pairs with the existing air conditioner, then discovering the wireless features cannot talk to the roof unit.

Frequently Asked Questions
Can I use a house thermostat in my RV?
Generally no. RV systems run on 12-volt DC and use control wiring unique to each brand, so look for a thermostat made for your specific furnace and air conditioner.
What does single zone mean?
It means one thermostat controls one air conditioning zone, which is how both Dometic CT listings here are described. Coaches with several air conditioners may use multiple controls or a more advanced system.
Is a smart thermostat worth it for an RV?
If you want to adjust the temperature before arriving or keep pets comfortable, wireless control helps, though it depends on having a signal or a phone nearby. If you want simplicity, a basic dial is just as dependable.
How do I find my part number?
Remove the faceplate and look for a label on the back or the housing. Photograph the wiring before disconnecting anything so you can match it later, and switch off the power to the coach circuit before you remove screws.
