Certainly, at one point in time, you must have noticed a red, green, or yellow light blinking on some of your electric appliances and wondered what those lights are and their meaning. Well, those lights are known as Led lights, and they flash or blink whenever current flows through in one direction.
You will also find this light on HVAC systems, including your heat pump. Unfortunately, not everybody understands what it means when these lights flash and would often ask questions like why is my heat pump light flashing? What does the red light on my heat pump mean? Some of the questions will be treated in this article.
Why does my heat pump light flashes?
A flashing light on a heat pump may be an indicator that the battery either has a defect or the battery is low and needs to be charged. Since this is usually a minor problem, it will be best to first check on the battery before you start disassembling your outdoor unit for a likely problem.
A heat pump is composed of both electrical and mechanical components, which means at some point, your unit may suffer from electrical glitches.
If this is caused by a glitch, it can be resolved by resetting your system and then waiting for a few seconds to turn it back on.
If the light keeps flashing after the reset, then there’s more to it than an ordinary glitch.
Faulty outdoor unit
A malfunctioning outdoor unit can also cause your heat pump to a flashlight. Although when this happens, it may be hard to figure out that it is your outdoor unit that is faulty because your indoor unit will still be running.
The only difference is that the intensity of the heat may reduce. So, after checking up on your battery and some other likely trivial problems, you should also check on your outdoor unit.
Your heat pump is in defrost mode
Heat pumps are designed to defrost during cold weather automatically. A flashing light can also mean that your heat pump is defrosting. So when you see this light during winter, you may not have to worry as defrosting is part of the function of your device.
Lose the wire
Sometimes when you notice a flashing light on your heat pump, it may not require more than checking on the wires for possible disconnection. Loose wire can cause your heat pump to draw more than required electricity, and when this occurs, your heat pump will notify you by flashing the power light.
Why is my heat pump light flashing Daikin?
If you notice that your Daikin heat pump is flashing light, it can be because of any of the aforementioned problems. However, beyond that, other possible causes may include a dirty filter, leaking refrigerant, or a damaged power cord.
Why is my Fujitsu heat pump light flashing?
Your Fujitsu heat pump may start with a flashlight when it is in defrost mode. Normally, if this is a result of the defrost mode, the flashing shouldn’t last beyond 30 minutes. If, after waiting for this duration and you can still see the lights, it is recommended that you consult a technician or you look into any of the general causes explained earlier or you may try to find the fujitsu error codes to troubleshoot.
Why is the green light flashing on my Fujitsu heat pump?
If the indoor unit of your Fujitsu heat pump is flashing green light, this indicates that the intake filter has been removed while your unit is working.
Why is the timer light flashing on my Panasonic heat pump?
A flashing timer light on your Panasonic heat pump could be an indication that there is an error condition problem. You can pinpoint the exact error with the help of your remote controller.
Why does my light flicker when my heat pump comes on?
A heat pump is among the most energy-draining household appliances. When you turn them on, they consume more energy in their first cycle, and that is why you may see their light flicker. Ideally, the flickering should not take more than a few seconds.
How do I know if my heat pump is bad?
Increase in energy bill
Normally, heat pumps and air conditioners account mostly for the overall expenses we pay on energy bills. Usually, homeowners don’t have a problem with this because it is expected. However, when there’s a sudden increase in energy bill with no extra usage, then it might be worrisome.
When any component of your heat pump requires repair or ordinary cleaning, there may be a surge in the amount of electricity used by your unit because they will be working harder than usual. Please read our previous ac hacks to save electricity guide if you need further help.
Although heat pumps do make noise, there are times they make sounds that are not typical of heat pumps. It is an indication that your heat pump is bad. Different maladies lead to different sounds.
For instance, when the noise is caused by a loose fan belt, your heat pump may give out a rattling sound and screeching sound from a poorly lubricated fan motor.
When there’s poor airflow, the intensity of the heat produced by your heat pump will be lower than usual, and there are lots of issues that may lead to this. Mostly when this occurs, it is as a result of a blocked outdoor unit, dirty coil, dirty filter, or faulty blower motor.
Heat pumps don’t produce fumes, so if you smell any strange odor coming from your unit, it could mean that something is wrong. Several factors may be responsible for this; it could be that mold is growing in your unit and needs to be cleaned or that something is wrong with the electrical component of your device.
Most time, when this happens, it gives off a burning smell and usually requires urgent attention to forestall fire hazards.
What does the red light on the heat pump mean?
The red light on your heat pump can mean two things. It is either your heat pump is having a problem defrosting, or the outdoor unit is completely locked-out.
Why is my heat pump not turning on?
If you can’t turn on your heat pump, it is a result of any of the following reasons.
- You have put the thermostat in the wrong setting.
- The condensate drain pan of your heat pump has overflowed.
- Your heat pump’s evaporator coil has frozen.
- Tripped circuit breaker
- Crucial components of your heat pump like the capacitor and reversing valve have stopped working.
