Unit has been working fine for several years. Humidity is 75 setting is 60, but the compressor will not come on. When I shut it off for several minutes, then restart it, the compressor comes on for a short period. Then just the fan runs.

Verify the humidity reading with another device. Perhaps the humidity sensor is dirty or bad.
Another possibility is the switching device that runs the compressor and fan is shorted. If it's a mechanical relay, the contacts may have welded together, or if it's a solid-state relay, it's got a punch-through or meltdown in a device junction. My guess is it's a mechanical relay since you mention it used to click on and off and now you don't hear that. The relay may be on the control board, or it may be mounted separately - I don't have a photo or diagram of the inside of your model available.
could you be mistaking the room humidity indicator for the time? reason I ask is on these one display units this happens more frequently than Id care it too , the one display shows both time and room humidity also set point humidity , the only way one can tell is on some models there is a tiny light that shows up next to labeled function , easy to miss It , also if your machine is sort of new (last few years) it has been decided that it's more efficient to let the circulation fan run all the time , regardless of room humidity . this makes it a little annoying (noise) but they do cycle the compressor to regulate the room humidity
It may just be the fan running and not the compressor. Some unit's are designed that way, so that air is constantly moving and when the humidity level rises above what you have it set on, the compressor will automatically turn ON and remove that moisture. Wants it's back to where you have its set, the compressor will turn OFF. Check your Owner's Manual to see if your model has that feature.

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.
There is some service that you can do ... Clean the filter and the cooling coils, regularly. Check the humidity level that you have the unit set on. It may be set to low and there's just not that much humidity in the air at this time, for it to collect. From what you said, it sounds like you may have it set on continuous cycle which could account for the lack of a lot of water in the bucket. In continuous run, the fan stays ON all the time. It's supposed to do that, so that the air is constantly moving and the sensor only turns the compressor ON, if it senses a humidity level 5% higher than what you have it set for. Try running the unit on a 1 or 2 hour cycle (if your model will do that) rather than continuous cycle.
Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing
use a jumper cord and go directly to the compressor to see if it will run. if it don't run, open up the motor box and see if there is a klixon overload inside. this should be normally closed. if it isn't replace it. the klixon is a thermal overload cutout. it usually trips because of high winding temperatures and protects the motor inside. the compressor is a hermetically sealed unit. no, or little freon will cause the motor to overheat.
I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad. Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.
