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

Condensate pump runs but does not pump

I have only seen a couple but they were pressed on the shaft. Superglue might work.

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

Little giant over runs with water, but runs when i lift the lid. ? help !

It sounds like the float assembly is getting restricted somehow. Check to see if it is hitting the cover and/or binding over normal up/down travel.

Aprilaire 500 water won't stop running down to condensate pump

Hello, sounds like rhe solenoid valve is stuck open. This will keep water flowing through the humidifier even if the Furnace is off. The solenoid valve will have to be replaced.

My Little Giant pump (554405) is connected to our furnace/cac collecting condensation. It's been working fine for about 5 years. Now it keeps turning on for about 2 seconds and stopping only to repeat...

There could be gunk in the bottom....then the float does not work right and the pump will not pump either...

remove the pipes and/or hoses and then the screws that hold down the top....clean the inside really well and reassemble... that may work,,,, but it may already be burnt up...

if cleaning does not work the replace the should be able to buy a new one at a HVAC supply house or some place like HD or Lowes...they will be in the 50.00 or less range...

I woke up to a wet floor. The furnace is working well. It has a Hartell KT-15-1ul automatic condensate pump, could this pump have quit working?

Have you condensate pump checked for a leak in the
mechanical seal. The pump may still be working, I hope.
Have this checked ASAP.

Little Giant Condensate pump runs for 1 sec when res not full

Is there a check valve in the pumps discharge fitting? If there is it may be stuck open or broken allowing some of the water to return to the reservoir once the pump shuts off which then may lead to the brief cycle between full cycles.

If there is not one, install one to keep any water from backing back into the reservoir and that should stop the short runs.

Condenser dryer keeps tripping the trip switch.

this is often because water has got into the fan area and is being thrown up on the heater by the fan.
take heater cover off and dry off.
take condensor out. in the space at the back, you will find a hole where condensate runs into pump chamber. this hole maybe blocked.
otherwise, check operation of pump
