ways to manage issues with
Higher expenses, bad performance and poor quality air all recommend that there is something
wrong with your system. In a central air system, the condenser is one of the main parts that gets
the whole system going. Just one issue with that can influence the entire system's efficiency.
Here, we've noted a few of things that you can check yourself. Your understanding with this may
be all that you need to get it working perfectly once more.
• If the issue is with the condenser fan (if it's not running), make sure that the thermostat is set to
cool which the level is at a temperature level lower than the room temperature suggested on it.
• If your thermostat is set to cool but it still will not run, provide your refrigerant pressure a check.
It needs to be equivalent to the ambient temperature level. Inspect the low and high-pressure cutouts. After, see to it that the control voltage to your thermostat is correct and the condensing unit
has the right line voltage.
• Have a look at your merges, breaker and disconnect. If you have actually a blown fuse or a
tripped breaker, the problem with the condenser may be an unsuccessful compressor or motor, or
a grounded or shorted wire in the device.
• Turn the unit off, then examine the terminals if there are any shorted, grounded, or open
winding. Next, inspect the wiring for any burned, grounded or shorted adapters or wires.
• If all are great, open your condensing system and ensure that the main supply voltage is right. If
not, fix it.
• If the primary supply voltage is fine, go to the thermostat and fix the control voltage. If it's
correct, then verify if it's reaching the thermostat. You may have a failed thermostat, or a wire in it
might be broken.
• Once you have verified that it's reaching the thermostat, see to it that the contacts are closing
when you turn it on to cool. If not, you have finally found the problem with the condenser.
• However, if that's working fine also, turn your system on, set it to cool, go to your compressor
specialist and examine the voltage reading. If the specialist fails to energize, you have a failed
• If your service provider coil does not have a control voltage, get a voltage reading across a
security. You have found an open one if you do discover a voltage reading.
• An open voltage monitor or a phase protection may be brought on by an intermittent issue, or
you may have an unsuccessful security. If the safety is open even when the present voltages are
simply within the safety levels' variety, then it has currently failed. Check if it's a manual reset type

• If you have an open high-pressure safety, inspect your condenser fan, clean the coil if it's dirty,
and make certain that the standing pressure for the refrigerant is right.
• Inspect the condenser coil's temperature. The high side's standing pressure must be equivalent
to it. If it's not, the system may be polluted with non-condesibles, air, or blended refrigerants. You
will have to fix it if it is.
• If it's the low-pressure safety that's open, then check the pressure on that. An automatic reset
security will reset and close it if the pressure is above 55 psi. Because it is open, then the security
has actually failed.
• If it's the oil pressure security switch that's open, leading the oil level to regular if it's low. When
you run the unit once more, see the oil level.
• If the oil remains in the system and the system runs in full load, the oil will go back to the
compressor. You will have to remove it so you can keep the proper oil level.
• Simply close to the compressor terminals is the compressor protection module. This security is
developed to protect the compressor from any electrical failure and open the control circuit. If this
is open, discover the reason and remedy it.
• If the compressor doesn't run even when the specialist pulls it, ensure that the compressor
terminals have the proper voltage. If it does, check the compressor terminals and see to it that
that has a right voltage.
• Now if it's the condenser fan that won't turn, examine if the motor turns by pushing on the blade.
If it will not, then it requires replacement. If it does, inspect the relay so that it has the correct
• If the relay does not stimulate and close and there is a control voltage, that indicates that it has
failed. If it doesn't have control voltage, examine your control circuit. Y ou may have an
unsuccessful low ambient control.
• If it stimulates, the load side voltages should be proper and they must be reaching the motor
• If all are great, turn it off and get a resistance reading on the windings. You may have a failed
fan motor.
• You might need to change the run capacitor if there is one so you can see if the motor runs.
• If you have a run capacitor, you must be able to take an amp make use of the leads. If not, the

capacitor is bad, or you may have a failed start winding.
If the problem with the condenser is electrical, by following these steps, you need to be able to
discover it. Remember to inspect the filter, blower, evaporator coil, and ducting so that device will
begin running correctly when you turn it on. However, note that when you are not familiar with any
of the above-mentioned set up, it is advisable to have actually the problem dealt with by your
trusted A/C specialist making sure that the problem is properly dealt with.
