Can I replace my RV thermostat with any thermostat?

You cannot use a standard house thermostat in an RV. RVs frequently employ smaller thermostats and less complicated cooling and heating systems.

Some thermostats can be used in either setting, and many RV thermostats can also be applied in mobile homes.

The sort of heating and cooling system your RV has, the brand and model of the RV, and whether the replacement thermostat is battery-operated will all affect how efficient the house thermostat will be.

Before making a purchase, confirm the specifications and recommendations from the manufacturer.

Why is my camper thermostat not working?

Dead battery

Modern digital thermostats need batteries to run the control unit. It is a good idea to swap out the batteries and double-check all the broken functions.

The thermostat appears to be dead when the battery is completely depleted. Look at your thermostat’s digital screen; if it is glowing, then the batteries are okay.

However, the internal bulbs may have an issue if the sidelight or backlight is dim. The lack of data on the screen indicates that the thermostat is not sending any signals, and the problem could be with the screen.

The positioning of the thermostat

Your thermostat may not work because it is in the wrong spot. Your RV’s thermostat panel may be hit directly by the sun, or defects or openings beneath the thermostat could permit cooler air to seep in and change the readings.

These situations can alter the thermostat’s internal temperature, giving the impression that the thermostat is broken and producing inaccurate results.

Circuit breaker trip

It’s easy to discover if your furnace’s heating and cooling circuit are silently tripping. Reset the thermostat if one or more have tripped, then inspect the thermostat and any associated equipment.

Although it could be fine for cooling, it may be more susceptible to tripping when the furnace starts to heat up and you need extra power.

Will a Domestic thermostat work with a Coleman AC?

 A Coleman RV air conditioner can take the place of a Dometic thermostat. A converter kit is vital in making a domestic thermostat replace a Coleman AC.

Using the conversion kit, you may change the Dometic air conditioner into a Coleman air conditioner.

The Coleman Mach Air-Vantage conversion kit is the one that you will need for this change. Thanks to the Coleman Mach Air-Vintage converter, you can use the domestic thermostat and the Coleman AC.

Rv Access last for three to five years based on the weather, storage, and how often you use them. On the other hand, some RV air conditioners are solid and, with proper care, can last for as long as ten years.

Who makes Coleman Mach?

Coleman is owned by AIRXCEL, a company that produces RV goods in various forms for both retail and industrial use.

Thor Industries now owns AIRXCEL after buying the brand as part of a calculated strategy to reduce its reliance on other parties in the supply chain.

They no longer rely on outside sources for necessary items such as thermostats, air conditioners, sealants, water heaters, and other things.

In its factory in Wichita, Kansas, they have produced more than 7 million air conditioners. They are one of the top RV air conditioner producers in the entire RV business.

How to troubleshoot the Coleman Mach thermostat?

#1. Troubleshooting for thermostat not functioning

Adjust temperature

First, make sure the thermostat reads the appropriate temperature for the surroundings. You might have to change the setting to activate the thermostat if it matches the current temperature.

An automatic setting should select the proper temperature for the conditions if you struggle to find the right environment or remember to make the necessary adjustments when in a new place.

Find a good spot

It may read the temperature to be much warmer than it feels in the rest of the car/house if it is placed in a location where the sun shines through the windows.

Select a location that accurately reflects the current temperature and doesn’t get excessively hot or chilly.

#2. Unresponsive thermostat

The most frequently cited problem is the thermostat’s abrupt shutdown and lack of response.

It can mean the appliance isn’t getting the power required to function. Here are some ways you can troubleshoot:

Replace batteries

If the device is battery-operated, you should ensure the batteries are functional. It could just be that they need to be changed, and new batteries will restart your device.

Check the current flow

If you have a voltmeter, you can use it to measure the current from an outlet powered by the mains.

This current should be flowing steadily and at the intended output rate. An incorrect level or erratic electricity flow could indicate a problem with the outlet, which would require additional inspection.

For the remainder of your trip or until the problem can be checked by a professional, you should use a different outlet if you notice an issue with an outlet.

Use a small lamp that you can put into the outlet and watch to see if the light turns on or not if you do not have a voltmeter to check your outlets.

Keep an eye out for a while to see if the current has changed. The lamp light will start to flicker as a sign of this.

It is wise to check other outlets in your car as well. If the same problem occurs on multiple outlets, it’s possible that your generator/battery, whichever you’re using to power your vehicle, is to blame.

Ask the park owner to look into the problem if you are connected to a power source inside the RV park and you detect a problem with several outlets. If the problem is not fixed, move to a different location.

Check the wires

If the device is mains-powered, you must ensure that none of the cables or connections appear to be frayed, scraped, detached, or corroded.

When there is only a loose wire, the user might be able to fix it himself. However, if there are any indications of harmed or corroded wiring, the machine will require professional repair or replacement if it is beyond repair.

#3. No display on the thermostat screen

When your thermostat screen is not working, it can be difficult to identify the reason. Try following the guidelines on troubleshooting unresponsive thermostats and if it is not fruitful, swap the fuse and do a reset.

#4. Do a reset

When your device starts acting up, there may be a problem with the configuration files kept on the device.

It is straightforward to perform a reset if you think this might be the issue. If a reset doesn’t work, it might be worth buying a new fuse, as the old one might be the problem.

How to install Coleman Mach thermostat

  • Cut off the power to the air conditioner.
  • On the new thermostat, disentangle the thermostat’s face from the rear.
  • Pull the old thermostat face off from the back.
  • Remove the screws holding the back mounted to the wall.
  • To simplify, take images of the wall-mounted wiring to identify which wire connects to which color or unplug the cables one at a time and attach them to the new thermostat.
  • Check the current temperature in the room, adjust the furnace and fan to the appropriate speeds, and set the temperature to cool or heat.
  • After finishing, screw the thermostat back to the wall and secure the face.

How to reset Coleman Mach thermostat

Turn off the thermostat before removing the fuse to ensure no electricity flows through the machine.

Give the gadget a minimum of five minutes before doing anything, then put in the new fuse and turn the power back on.
