Coleman central air conditioner problems. Coleman is one of the first companies to build and market an air conditioner that most people can afford.
Across a range of units, its 16.4 SEER (Seasonal Energy Efficiency Ratio) ratings could be classified as “average,” but this brand has such a long history of making A/C products.
That don’t waste energy and remain efficient while they last, you can rest assured knowing you’re making a smart purchase whenever you buy one of its AC products.
Coleman central air conditioner problems
Here are some common issues and their solutions.
Coleman Condenser fan motor issue
If the capacitor is not up to par, the fan may run noisily, overheat or stop completely.
To determine whether the capacitor has gone out of commission, inspect the capacitor. If it looks deformed or has become damaged, replaces it.
If the run capacitor has overheated, it’s likely that the fan motor is noisy, overheat, or won’t run at all. Inspecting the run capacitor will determine if there are signs of overheating like bulging or leaking.
Check the incoming voltage to the motor with a multimeter to determine if the condenser is working.
Make sure the capacitor is not the cause of the problem if the condenser fan motor is not receiving the correct voltage. Replace the condenser fan motor if the capacitor is not bulging or leaking.
Faulty Condensing unit
Thermostats have sensors and wires that can detect if they are malfunctioning or need to be replaced. When their functions stop working, the furnace and condenser unit will be unable to run properly.
The central condensing unit uses electricity to run the compressor, condenser fan motor, and any included fuses in the disconnect box.
If the unit is blocked outside (such as a window or door being closed) then it will not turn on.
The air conditioning’s disconnect box contains a fuse that may need to be replaced if the unit will not turn on and you can see that it is outside (such as a closed window), or hear that it has tripped.
Test the continuity of the fuse with a multimeter to see if it has blown. If there is no continuity on the fuse, replace the broken one with one of those located in the compartment next to it.
Coleman Central air conditioner produce noise
Over time, the bearings in the AC condenser fan motor can wear out. A grinding sound is heard when the bearings are worn out.
Try rotating the motor by hand to inspect the bearings. If the motor does not rotate smoothly, it needs to be replaced.
The blade of the condenser fan motor might be defective or loose. One way to check is by wiggling the shaft of the motor. If it’s loose, tighten or replace its set. If it’s still making noise, replace the blade with a new one.
A low voltage signal is sent by the furnace control board to the contactor. When it receives the signal, the contactor closes the circuit, sending voltage to the condenser’s components.
The contactor is integral in providing power to those components and will make noise if it is not functioning properly.
If a condenser fan is making noises but not cooling, then there is a chance this means that there may be an issue with the contractor.
To be sure, test for continuity using a multimeter; if there are no indications of continuity when tested, then you’ll need to replace it.
If you notice that your fridge isn’t cooling properly, there may be a problem with your dual-run capacitor. This component is found beneath the fan motor, so it can be tricky to find.
If the capacitor has failed, it might be bulging or leaking. Your refrigerator will most likely still have power and appear to work normally except for the cooling part.
The central air conditioning system, which consists of a condenser, fan motor, and compressor, is connected to AC power by way of a disconnect box that enables the outside components to be turned off.
The disconnect box, in turn, utilizes fuses (or breakers) to direct power to or away from the above-named components if any of these devices stops working there could be a wire shorting out, a blown fuse, or even an electrical fire.
Verify this possibility by testing your fuses for continuity with a multimeter. If any fuses are not functioning as they should, then they need to be replaced.
