6 Common Mach Air Conditioner Troubleshooting Problems (Coleman Mach Air Conditioner Not Working)
Below are six common Mach air conditioner problems for troubleshooting:
1. Coleman Mach Air Conditioner Not Turning On
A Coleman Mach air conditioner doesn’t fail to turn on unless something is wrong. While it’s often a case of the unit not getting power, it could sometimes be a component malfunction.
Here are the likely reasons why your air conditioner won’t turn on:
Power outage – You’re Coleman Mach won’t turn on if there’s no power. So, you have to check if there’s an outage. If not, then consider the other issues.
Unit not plugged in – It’s easy to forget to plug in the air con and assume that something is faulty. So, check the power cable to ensure it’s plugged in and turned on.
Tripped breaker – The breaker flips off during an overvoltage or power surge. That’s likely to stop the AC from turning on.
Blown fuse – An overvoltage or power surge will likely prevent the air conditioner from starting. You can test it with a multimeter to determine whether it has continuity.
Non-responsive remote – If the remote control doesn’t respond to your pressing, it won’t turn on the air conditioner. In most cases, the issue is exhausted batteries.
Faulty wiring – If there’s a problem with your electrical wiring, the air conditioner won’t turn on. That includes loose and rodent-chewed cables and broken wires.
Bad thermostat – With the thermostat monitoring your AC’s temperature, its defectiveness can prevent the AC from turning on. So, you may need to troubleshoot the air conditioner thermostat.
Bad run capacitor – The run capacitor connects the compressor through electrical leads. If it’s bad or bent, the compressor won’t run, and the AC will not turn on.
Fix
Confirm if you have electricity or if there’s a power outage. If it’s not the latter, ensure the unit is correctly plugged into the power socket. If it still won’t turn on, check the circuit box for the tripped breaker and reset it.
Then test the thermal fuse with a multimeter. If the fuse lacks continuity, replace it. Also, test the remote control to see if it’s working. You can replace the batteries if it has been a while (over a year).
If the unit still doesn’t turn on, talk to an expert to check for faulty wiring or a potentially bad thermostat or capacitor.
2. Coleman Mach Air Conditioner Won’t Turn Off
Sometimes the Coleman Mach would turn on but fail to turn off. If that’s the case, the likely causes are as follows:
Dirty condenser coils – If the condenser coils are filthy, they fail to dissipate heat well and force the compressor to run continuously to try and cool the unit.
Defective thermostat – Sometimes, the AC may turn on when the thermostat is faulty but unable to turn off as the thermostat cannot monitor the temperature changes.
Defective thermistor – The thermistor also detects the temperature changes like the thermostat and will prevent the AC from turning off if it is faulty.
Bad relay board – If the relay board is faulty, the compressor won’t get a consistent voltage supply, which can stop the AC from turning off.
Failing temperature control board – A bad temperature control board may cut off the compressor’s voltage supply, causing the compressor to run on stop.
Failed control board – The main control board also cuts off the compressor’s voltage supply when faulty, and that stops the AC from turning off.
