If your Coleman Mach AC fan is not functioning, there are several troubleshooting steps you can take to identify and resolve the issue. Start by examining the circuit breaker; a tripped breaker may be the reason your fan is not receiving power, so resetting it may restore functionality.
Next, ensure that all connections and wiring associated with your Coleman Mach AC unit are secure and intact. Loose or damaged wires can impede the fan’s operation. It’s also vital to check the fan motor for any visible damage or obstructions; debris or defects can prevent it from functioning correctly.
If these preliminary checks don’t rectify the problem, the issue may lie within the internal components, potentially necessitating the replacement of either the blower motor or the capacitor. These parts are essential for proper fan operation, and a malfunction could severely impact the performance of your Coleman Mach AC.
Finally, if these troubleshooting steps fail to resolve the issue, it may be time to consult a professional HVAC technician. An expert can provide a comprehensive diagnosis and implement the necessary repairs, ensuring your Coleman Mach air conditioner is up and running efficiently once again.

Coleman Mach Ac Not Turning on
If your Coleman Mach air conditioner isn’t turning on, you should first check to ensure the power source is functioning properly.
Check for a blown circuit breaker or tripped GFCI outlet and reset if necessary.
How to test RV AC fan motor?
Safety first: Before you start, ensure that the RV’s power source is disconnected to avoid any electrical accidents.
Access the Fan Motor: Depending on your RV’s AC unit, you may need to remove an access panel to reach the fan motor. Refer to your RV’s manual for specific instructions on accessing the AC unit components.
Visual Inspection: Once you have access to the fan motor, perform a visual inspection. Look for any signs of physical damage, such as frayed wires, burnt components, or debris obstructing the fan’s movement.
Check for Power: With the RV’s power source reconnected, turn on the AC system. If the fan motor is receiving power, you should hear a humming sound and see the fan attempting to spin.
Multimeter Test: To perform a more comprehensive test, you can use a multimeter to check the fan motor’s electrical continuity. Here’s how:
- a. Set the multimeter to resistance (ohms) mode.
- b. Disconnect the fan motor’s wiring from the power source.
- c. Identify the motor’s leads. There are usually three: high, medium, and low speed.
- d. Touch the multimeter probes to any two of the motor’s leads. Take note of the resistance reading.
- e. Repeat the process with the other lead combinations (three total).
- f. If the multimeter shows infinite resistance (OL) in all combinations, the motor’s windings may be open, indicating a faulty motor.
Capacitor Test: Many RV AC fan motors use capacitors to start and run. A faulty capacitor can cause the motor to fail. To test the capacitor:
- a. Disconnect the capacitor from the fan motor.
- b. Use a multimeter in capacitance mode and touch the probes to the capacitor’s terminals.
- c. Compare the reading to the capacitor’s rated capacitance. If the reading is significantly lower or higher, the capacitor is likely faulty and needs replacement.
Check for Obstructions: Sometimes, the fan motor may appear faulty due to debris obstructing its movement. Carefully inspect the fan blades and surrounding area to ensure there are no obstructions.
Motor Replacement: If all tests indicate a faulty motor or capacitor, it may be necessary to replace the fan motor. Contact your RV manufacturer or a qualified technician for the appropriate replacement part and installation.
How Do I Reset My Coleman Mach Air Conditioner?
If you need to reset your Coleman Mach air conditioner, the process is actually quite simple.
Begin by switching off the power supply and disconnecting the unit from its electrical source.
Next, locate and remove any debris that may have collected around the condenser coils or fins on the outside of the unit.
After this step has been completed, turn back on your power supply while holding down both buttons located on top of your air conditioner for approximately five seconds.
This will reset it to factory settings, allowing you to enjoy cooler temperatures in no time!
