Either drain tube is plugged so that it can't pump out or the float switch is hung up in the on position. See if it is full of water or empty. Full, check the hose. Empty, check the float

Why my heat pump only heat in emergency heat only,the condens is cutting off and on


It sounds like a maintenance issue with your heat pump, its clear that the unit is trying to run but one of the safeties is shutting it down trying to protect itself. most heat pumps are equipt with a High press lockout usually a manual reset ,a low press, cut out switch resets on rise of press automatically. Causes of LPCO Extremely dirty condenser coil or evaporator coil, Loss of fan on condenser, Low refrigerant charge. A competent Service man should be able to locate and correct this problem. A seasonal check up on the unit avoids these problems.

KNOWING ABOUT CONDENSER


What is a condenser?
Is a device or unit used to condense vapor into liquid. A condenser is simply one component of an air conditioner. Whether you have an outdoor air conditioner or a window unit air conditioner your air conditioner contains a condenser.
Condensers are used in outdoor air conditioning systems as well as heat pump systems. Condensers in an air conditioning unit have very few controls. They will have an on and off switch. Occasionally these air conditioners will also have a brown out option. This option shuts down the compressor when the electrical current is low.
A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. A condenser is a major component in a air conditioning or heat pump unit. It moves air across the coils to facilitate the transfer of heat.
In a heat pump unit the condenser has a few more features. It will have a reverse valve that allows the unit to switch back and forth between air conditioning and heating. Even when the unit is heating, it uses the condenser for defrosting the coils. If the coils become layered with frost it will effect the units effectiveness this is defrosted when the reverse valve switches to air conditioning mode to move the hot gases through the coils melting the built up ice. It will automatically switch back to heating mode once the ice is cleared to once again heat the home.
To keep your unit in good operating condition it is vital to keep the area around the condenser clear of all debris as well as keeping the filter clear of dust and dirt. A clean machine makes a happy machine. A happy machine will keep you cool during the summer months and warm during the cold months. It is suggested to change the units filters when they become dirty, depending on your area and conditions near your home this may be as often as once a month or as seldom as every 3 to 6 months. You will have to pay close attention to your units needs to decide the right time to change or clean your unit’s filters.
It is very important no matter what type of unit you have to prevent the blockage of the condenser. If the condenser becomes block it can effect the units efficiency or even cause the until to completely fail. For this reason it is one of the most important components of a cooling or heating system. A condenser allows the maximum airflow to the unit.
Keeping you condenser in good running condition will not only prolong the life of your heat or cooling system but also provide you with the most efficient heat and cooling system saving you money on heat and cooling.www.victorwod1234.blogspot.com

Why your unit is freezing up.


To understand why your AC or heat pump is freezing up, it helps to know how your system works.

There are 7 major parts to an AC system, 9 with a heat pump.

1 - Condenser/heat pump (The outdoor unit)
2 - Air Handler (the indoor unit unless the system is a package unit, then all is outside in one system. The air handler is usually found under the home, in an attic, or in a closet.)

In the condenser are the following major parts.

3 - Compressor
4 - Condenser coil
5 - Condenser fan
6 - (HPs only) reversing valve

In the air handler are the following major parts.

7 - Blower motor
8 - Evaporator coil
9 - (HPs only) electric heat strips

Some systems known as "dual fuel systems" use another heat source in place of the heat strips, usually a gas furnace. I will address gas furnaces in another post.

When an air conditioner is operating properly several things are taking place.

1 - The compressor is compressing or "pumping" refrigerant through the system.

2 - through changes in pressure, the refrigerant makes the evaporator coil get very cold, and the condenser coil gets very hot.

3 - The blower motor/fan circulates air across the evaporator coils, as the room temperature air (Also known as "indoor ambient") goes through the cold coil, it exits, cooled approximately 15 to 20 degrees cooler than when it entered. (In a ducted system, the blower is also the fan that circulates the air throughout the home.)

4 - The condenser fan circulates air across the condenser coils. As the outdoor air goes through the condenser coil, it removes heat from the coils that are very hot. This in turn removes heat from the refrigerant so it can run its cycle again, and through pressure changes, cool the evap coil.

5 - With a heat pump, the reversing valve reverses the flow of refrigerant in the condenser and evaporator coils.
In AC mode, the evaporator coils get cold, and the condenser coils get hot. But in heat mode, the evaporator gets very hot, and the condenser very cold.

Now, whichever coil is getting cold will freeze up if there is inadequate air flow across the coil, as the refrigerant in it is far below freezing, and there is not enough airflow to keep the humidity in the air from freezing on the coil.

Things that can cause poor airflow are,

1 - Dirty/clogged coils
2 - dirty/clogged filter (will only effect evaporator coil)
3 - Closed/blocked vents (will only effect evaporator coil)
4 - Malfunctioning or dirty fan

Low refrigerant will also cause a coil to freeze up, reduce efficiency and cause the system to run for long periods of time. Not to mention, shortening the life of the unit.

With a heat pump, in heat mode only, the condenser (outdoor) coil will routinely begin to freeze up in cold temperatures. This is due to the fact that the refrigerant is below freezing, and the cold outdoor ambient temp is not warm enough to keep the condensation in the air from freezing on the coil.

Note, a properly working AC should never freeze up.

A heat pump is equipped with defrost controls to prevent ice buildup.
Some are controlled by timers, some by temp.

When a HP is going into defrost mode, the condenser fan shuts down, the reversing valve reverses the flow of refrigerant and the once cold condenser coil now gets very hot, defrosting the coil. (Many people have said this process sounds like the unit is coming apart, or about to explode and are frightened by the "smoke" which is really just steam from melting ice that comes off the unit.)

During defrost mode, the secondary or "auxiliary" heat comes on to ensure that you are still getting warm air from the vents. (Again, this can be electric heat strips or a dual fuel system)

If you are experiencing cold air from the vents during defrost, that means your auxiliary heat is malfunctioning.

The auxiliary heat is used for three purposes.

1 - during defrost mode to maintain warm airflow (automatic)
2 - when the HP cannot maintain the set temp due to extreme outdoor temps. It comes on when the indoor temp drops several degrees below the set temp on the thermostat (automatic)
3 - For emergency heat source when the HP is not working. (Manual)

To recap....

Iced up coils?

Poor airflow
low refrigerant
Malfunctioning fan
failing defrost system


There are two things that can be done in a pinch to help de-ice frozen coils. This may get you by until the repairman can get there, or you can fix the system if you are a do-it-yourselfer.

HPs frozen outdoor coil in heat mode, not going into defrost?

Cover most of the vents, and turn the system onto cooling mode until the outdoor coil is thawed. then uncover vents and return to heat, or emergency heat. (this usually takes 15 min or less)

Frozen coils in AC mode with a heat pump?
Turn the system to heat with the thermostat on just high enough to get the system to come on. (again, usually takes 15 min or less to thaw.)

AC only, with frozen evap coils? (this can sometimes be seen frozen all the way outside to the compressor on the copper lines.)

Turn the system off, and the fan switch from "auto" to on".
This will usually defrost the coils within 1 to 2 hours.
(If your system has the furnace in line before the evap coil, turn the system to heat, and the furnace will defrost the coil within minutes.)

What makes the condenser fan shut off but the compressor keeps running but not every time


Condenser fans cycle on and off to control the temperature/pressure of the refrigerant in the condenser. This is normal operation.

As to cooler weather start up and tripping the breaker; how cold is it when you are running it? If it is too cold you could be pumping liquid refrigerant back to the compressor, slugging it and causing it to trip a breaker. However, many things can cause an air conditioner to over-amp and trip a breaker but this tends to be more problematic as the weather is hotter.

Toto air conditioner


I'm not sure if this unit has a condensate pump. If it's located below grade and drains to the outside it likely should have one. The condensate pump may be bad or the pressure switch that activates the pump is bad. The pressure switch measures the amount of water in the condensate collection tank. It serves the same purpose as the float in a toilet. Also, check the condensate hose at the inlet of the pump. It could be a bad pump, a leak in the the collection tank, or a clogged hose.

I have a GrandAire and the aircon works fine; when I turned the heat on, it seems to work fine (warms the house), but the fan in the outside unit is not spinning when the heat is on...is this a problem?...


I think your unit is working in good condition. If you keep in cool mode the out door fan runs to condensate the heat in condenser by taking fresh air from the ambient. And when you keep heat mode, definitely the ambient temp will be too less.I fit takes from their then compressor will get frozting and it couldn't work properly. Depending on pressure increase, the fan will automatically run and stop. Don't worry. Thanks.

I have 4 ton carrier heat pump / puron. It is a new system been installed about 3 months. Live near Dallas Texas and lately the temp has dropped into the low 40's at night. The heat seems too be working...


The water is from humidity in the outdoor air which has condensed and then frozen to your heat pump outdoor coil. The heat pump will defrost occassionally, depending on how much frost has accumulated to the coil and will then generally drip off the unit and onto the ground. This is normal. To keep the water off the drive way may mean having to move the heat pump to a place where the condensation can run away from the drive area. Or provide some other means of redirecting the water.

Greenstar 30CDi conventional condensing boiler and the temperature is fluctuating rapidly and repeatedly between 37 and 63 degrees. It is set on 4 so just above 60 sounds correct according to manual....


It sounds like you have air in the system, Turn Boiler Off keep pump running and try to find a spot where you can bleed the air out.

If you dont have an automatic water fill installed then
you will have to add water by hand
