A heat pump Auckland provides warm and cool air as and when required to homeowners all year round.
If you are a homeowner in New Zealand facing this issue, you must know about the reasons why the
heat pump may not turn on.
The power switch is off
One of the most common reasons why the heat pump won’t start is because the power switch is in off
mode. Once flipped to the on position, the heat pump gets started.
Issue with the thermostat
● For the heat pump to turn on, the thermostat must be set at a temperature that is not too high
nor too low.
● Setting the thermostat to the correct temperature provides a signal for the heat pump to turn
on.
● In addition to the thermostat setting problem, there may be a problem with improper wiring,
incompatibility with the heat pump, or even an incorrect signal being sent to the heat pump.
● In these cases, it is best to call a professional, get the thermostat inspected, and replace or
repair it.
Dirty air filters
● The air filters are responsible for ensuring that the heat pump unit receives clean and fresh air.
● If the heat pump Auckland is not receiving enough clean air, it has to work overtime in order to
maintain the desired temperature.
● Excess load on the heat pump will cause overheating, and the heat pump will shut down
automatically.
● In order to avoid the heat pump working overtime, it is advisable to clean the filters frequently
or get them replaced if they have deteriorated.
Reversing valve malfunction
● The reversing valve is a key component of the heat pump.
● It moves the refrigerant, which is the cooling fluid of the system, in the direction in which it is
actually supposed to move.
● In the event of a faulty reversing valve, the heat pump may turn on in cooling mode but not in
heating mode, or vice versa.
● A malfunctioning reversing valve can also mean that the heat pump won’t start at all.
● In order to heat and cool the home properly, it is essential that the reversing valve is fully
functional.
Faulty starter capacitor
● The starter capacitor provides a signal (power) to the motor that drives the heat pump.
● The burst of energy needed to start the heat pump unit is given by the starter capacitor.
● If the starter capacitor is faulty, the motor won’t function, and the heat pump won’t turn on.
● If you detect a faint clicking sound coming from the heat pump when you try to switch it on, that
is a possible sign of a malfunctioned starter capacitor.
● Do not attempt to replace or touch the starter capacitor on your own.
● It has a lot of electric charge even if the power is disconnected.
● It is advisable to get a faulty starter capacitor replaced by hiring a professional technician.
Time delay relays
Time-delay replays prevent the heat pump from constantly switching on and off throughout the day. If
the time delay relay is stuck, the heat pump won’t start.
Frozen outdoor unit
● The outdoor unit of the heat pump Auckland is vulnerable to freezing during the cold winter
months there.
● A blocked outdoor unit of the heat pump with a thin layer of ice will result in frozen parts and
their malfunctioning.
● Thus, a frozen outdoor unit will not allow the heat pump to turn on.
● If the ice is left on the outdoor unit for a long time, it may cause permanent damage to the
entire heat pump system.
Low refrigerant
● The refrigerant plays a crucial role in the transfer of heat.
● In the event of a refrigerant leak, there won’t be sufficient heat transfer.
● With extremely low levels of refrigerant, the heat pump Auckland won’t turn on.
Malfunctioned components
● Even if one of the internal components of the heat pump unit malfunctions, it impacts the
functioning of the entire system.
● The malfunctioning of system components will result in the heat pump not getting turned on.
