Question about Kenmore 53509 Dehumidifier

3 Answers

Compressor does not start

We inherited a Kenmore 53509 dehumidifier with our home, so it is at least 2 years old, but we don't know if there was/is a warranty covering it. The fan still runs, but the compressor makes a noise like it is trying to start up and then conks out. The compressor continues trying to kick on every 15 seconds or so, until I get frustrated and turn the unit off. Every time we re-start it does the same thing. We've tried cleaning out the unit as well, with no change.

Is it worth servicing the compressor? Or more cost effective to just look into a new unit?

many thanks!

When the compressor tries to start, but only hums and draws a lot of current, the problem is most likely either a bad compressor or a bad run capacitor.

On the Kenmore model 25357510790, the capacitor is a 20 microfarad, 370V oil-filled capacitor, I believe. If you can get one at a reasonable price (around $25-35), it might be worth trying.

If the compressor is bad, the dehumidifier is not economically repairable, if not in warranty. Unless you know someone in the repair business that would do it for you for just the cost of the compressor, that is. ;<)

Other, less likely, problems:

A bad connection (high resistance, say, greater than 2 ohms somewhere in the circuit, including a bad plug or receptacle).

Sometimes the piston in the compressor will get stuck and a tap squarely on the side or top will get it dislodged and save a repair bill.

Some of these units have a 5 year compressor warranty on them including labor worth calling sears and seeing if it does have the 5 year on the sealed system

I have the a Kenmore dehumidifier sometimes it runs fine and other times just the fan runs not the compressor or just the opposite the compressor runs not the fan it is only 2 1/2 years old. What should...

Kathy, I'm not sure you have a problem with the dehumidifier. Depending on which mode you're operating it in, the fan will run in an effort to recirculate the air. If the humidity level rises above the level you have the unit set on, the compressor will then turn ON. This is particularly true, if the unit is operating in continual mode. Then there are other times the fan isn't active, but the compressor turns on when the humidity sensor feels a rise in humidity. So, for the most part, I don't think it's a problem.

Just be sure that you clean the air intake filter at least once every two weeks, during times of daily operation.

Hope this helped you. Please let me know. Thanks.

there is a freeze stat on the unit it connects to the evaporater coils it is suppose to shut of the compressor unit when it senses the temp is at freezing the idea is that the unit condenses moisture out of the air like your air conditioner for your house or car this part is dirty or malfunctionong

My kenmore dehumidifier compresor runs the fan runs but no water in the bucket . Compresor freon lines both same to have the same tempature ( flow and Return ) . Is a freon charge the answer ?

More than likely not. I would start by making sure all coils are clean, (both evap and condenser) and to make sure airflow is not being obstructed. Most factory charges appliances don't leak refrigerant and therefore should not have to be charged during there useful life. Hope this helps

The fan runs constantly. The compressor starts,

Check the compressor run capacitor first.

Help me fix my dehumidifier

What else is on the same circuit? Have you added any other appliances on that same circuit that were not on it before?

If no>>>you probably have a short in the unit, and it is grounding out>>>tripping the breaker before it starts a fire.

Also, check the breaker, they can go bad.
