Identifying the Need for a Reset
Sometimes, your trusty Coleman AC unit might act up a bit. Before you call a technician or start panicking, a simple reset might be all it needs. Knowing when a reset is the right course of action can save you time, money, and a whole lot of frustration. So, how can you tell if your AC unit is crying out for a reset?
One of the most common signs is when the unit simply isn’t cooling. You set the thermostat to a comfortable temperature, but the air coming out feels lukewarm or even warm. This could indicate a problem with the unit’s internal controls, and a reset might be just what the doctor ordered to get things back on track. Check if the unit is blowing air at all. If the fan isn’t running, it could be a separate issue, but sometimes a reset can address this as well.
Another telltale sign is unusual noises. While AC units aren’t exactly silent, you’ll get used to the normal hum and whir of the system. If you start hearing strange clicking, grinding, or buzzing sounds, it’s a good idea to investigate. These unusual noises could point to a malfunction that a reset might resolve. Sometimes, the unit might even start and stop abruptly, cycling on and off repeatedly. This short-cycling can be a symptom of various issues, and a reset is often a good first troubleshooting step.
Sometimes, the issue isn’t about performance, but rather unusual behavior from the unit itself. Perhaps the display on your thermostat is flashing error codes or behaving erratically. This could signal a glitch in the system, and a reset might be the simplest way to clear it. It’s always a good idea to consult your owner’s manual to decipher any specific error codes your unit might be displaying.
Finally, pay attention to any unusual smells. If you notice a burning smell coming from your AC unit, it’s crucial to turn it off immediately and call a professional. This could indicate a serious electrical problem that requires expert attention. A reset won’t fix this, and attempting one could be dangerous. However, if you detect a musty or mildew-like odor, it could signify a build-up of moisture within the unit. While a reset might not directly address the root cause, it can sometimes help by temporarily interrupting the cycle and allowing some of the moisture to dissipate. However, if the musty smell persists, you might need to investigate further for potential mold or mildew growth.

- Turn the power back on to the unit.
Locating the Reset Button/Switch
Before you dive into troubleshooting, it’s important to understand that not all Coleman AC units have a dedicated reset button or switch. Many modern units rely on internal circuit breakers or electronic controls to handle overloads and faults. However, some models, particularly older ones or those with specific features like a hard start kit, might have an external reset.
Where to Look
If your Coleman AC unit *does* have a reset, it will generally be in one of these locations:
1. On the Control Board
The control board, often located behind a service panel on the outdoor unit, is the brain of your AC. Some units feature a small, red or black button labeled “Reset” directly on this board. Be extremely cautious when accessing the control board, ensuring the power is completely disconnected before touching anything.
2. Near the Capacitor
The capacitor, a cylindrical component typically housed within the outdoor unit, helps start the compressor. Occasionally, you might find a reset button near this component. It may be housed in a small, weatherproof box or integrated into the capacitor housing itself. Again, exercise caution and disconnect power before inspecting this area.
3. On the Power Cord or Plug
Some portable Coleman AC units, especially those designed for RVs or camping, may feature a reset button integrated directly into the power cord plug or on a small box along the cord itself. This is a safety feature to prevent overloads and protect the unit from damage. Inspect the entire length of the cord and the plug itself, looking for anything labeled “Reset.” These buttons are often recessed to prevent accidental tripping.
This type of reset typically functions as a thermal overload protector. If the unit draws too much current, the reset button will trip, cutting off power. Before resetting, allow the unit to cool down for at least 15-30 minutes. This allows the internal components to return to a safe operating temperature and prevents immediate re-tripping. After the cooling-off period, firmly press the reset button. You might hear a click indicating the circuit has been re-engaged. If the unit trips again shortly after resetting, this signifies a deeper issue that requires professional attention. Do not repeatedly reset the unit, as this can cause further damage.
To help identify the location on specific models, refer to your owner’s manual. It usually contains a diagram or detailed instructions on finding and using the reset mechanism. If you can’t locate your manual, try searching online using your unit’s model number.
4. Types of Reset Mechanisms
There are a few different types of reset mechanisms you might encounter:
| Type | Description | Appearance |
|---|---|---|
| Button | Requires pressing to reset. | Small, round, often red or black. |
| Switch | Requires flipping a switch to the “off” position and then back “on.” | Small toggle or rocker switch. |
| Breaker | Requires flipping a breaker switch to the “off” position and then back “on.” | Similar to a household circuit breaker. |
If you’re still unsure after checking these common locations, consulting your owner’s manual or searching online for your specific model is the best course of action. When in doubt, it’s always safest to contact a qualified HVAC technician to diagnose and resolve any issues with your Coleman AC unit.

Consult your owner’s manual for the exact location on your specific model. If you can’t find your manual, don’t worry! Many manufacturers have manuals available online. Just search for your model number.
Powering Down the Unit
Before hitting that reset button, make sure you completely power down the unit. This is an important safety precaution. You can do this by unplugging it from the wall outlet, or if it’s a larger unit, switching off the breaker at your electrical panel. Give it a few minutes to ensure all power is drained. This prevents any electrical surges and helps ensure a clean reset.
The Reset Process
Now comes the main event – the reset itself. Once the unit is completely powered down and you’ve waited a few minutes, locate the reset button. If it’s a button, press and hold it for about 30 seconds. You might hear a faint click or see a light flicker, indicating the reset is complete. Some models have a switch instead of a button; if this is the case, flip the switch to the “off” position, wait 30 seconds, then flip it back to the “on” position. If your unit has a digital display, you might see a message indicating the reset is in progress or has been completed. If your unit doesn’t have a designated reset button or switch, you may need to simply disconnect the power for an extended period, usually around 30 minutes to an hour. This allows the internal circuitry to fully discharge and return to its default settings. Check your owner’s manual for specific instructions if you’re unsure about the process for your particular model. After resetting, plug the unit back into the power outlet or switch the breaker back on. Give the system a few minutes to initialize before turning it on.

Monitoring Post-Reset
After resetting your Coleman AC unit, keep an eye on it for a while to make sure it’s working properly. Pay attention to the airflow, listen for any unusual noises, and check that the temperature is dropping as expected. If everything seems to be back to normal, you’ve successfully resolved the issue. However, if the problem returns or you notice any new issues, it might be time to contact a professional for a more thorough inspection and repair.
Waiting for the System to Reboot
After you’ve taken the steps to reset your Coleman AC unit – whether that’s by switching off the power at the breaker, using the thermostat’s reset button, or disconnecting and reconnecting the power cord – the next crucial step is allowing the system sufficient time to reboot. Think of it like restarting your computer; it takes a moment for all the internal components to power back up and communicate with each other. Rushing this process can sometimes cause more problems than it solves.
So, how long should you wait? A good rule of thumb is to wait at least 30 minutes after powering off your unit before turning it back on. This timeframe allows the internal capacitors to fully discharge, which is essential for preventing damage to the unit and ensuring a clean restart. These capacitors store electrical energy and need time to release it safely. Imagine them as small batteries that need to drain before being recharged. If you try to restart the system too quickly, the stored energy can disrupt the startup process, leading to errors or even component failure.
During this waiting period, it’s important to resist the temptation to fiddle with the thermostat or the unit itself. Let the system rest undisturbed. This is a passive process, and your intervention won’t speed things up. In fact, repeated attempts to power on the unit too soon could trigger a safety mechanism, further delaying the reboot. Consider using this time to confirm that your thermostat settings are correct. You want to ensure that the desired temperature is set appropriately to avoid overworking the unit once it’s back online.
While the 30-minute wait is generally sufficient, there are situations where you might need to extend this period. For instance, if your unit has experienced a significant power surge or has been subjected to extreme temperatures, waiting an hour can be beneficial. This extra time allows all components to normalize and reduces the risk of further complications. Think of it as giving the system a chance to “catch its breath” after a stressful event.
Understanding the Reboot Process
Understanding what’s happening during the reboot process can help you appreciate the importance of patience. Here’s a simplified breakdown:
| Stage | Description |
|---|---|
| Power Down | Electrical power is cut off, allowing components to discharge stored energy. |
| Capacitor Discharge | Capacitors release stored electrical charge, a crucial safety and performance step. |
| System Initialization | Internal components power up and begin communicating with each other. |
| Self-Diagnostic | The unit performs internal checks to ensure all systems are functioning correctly. |
| Ready to Run | The unit is prepared to receive commands from the thermostat and begin cooling. |
By allowing your Coleman AC unit the appropriate time to reboot, you’re ensuring its longevity, promoting efficient operation, and preventing potential damage. So, take a break, grab a refreshing drink, and let your AC unit do its thing. The comfortable cool air will be worth the wait!
