Fan fixed but evaporator solenoid keeps activating at times

Can anyone please explain to me the purpose and why the evaporator solenoid on my dehumidifier activates? im sure its not a refrigerant issue since its only 4 years old but at times if its running alot it will turn the fan off activate solenoid(hear a shhhhhh noise at first thought it popped a line but apparently it dumps the refrigerant into the compressor bypassing the coils) and like 5 minutes later when the woosh sound is lower it turns off and reactivates the fan-compressor runs during this cycle when solenoids activated.

any help would be appreciated bc theres nothing out there and suprisingly the owners manual never even so much as mentions the solenoids presence

The purpose of the valve is to de-ice the evaporator and the valve is turned on by a timer usually. in normal operation, the evaporator builds up with ice (that is how water is extracted). when the valve operates, to put it simply, the hot gas is routed to the evaporator and hence melts the ice off

Why doesn't the unit cool when the coil temperature is at 40 degrees F.

You asked why your dehumidifier does not cool; it is not the purpose of a dehumidifier to cool the air going through it. It works like an air conditioner except the hot and cold air are not separated out. The cold [evaporator] coil is the first coil in the air stream where humidity [water] from the air collects just like it does on the outside of a glass of ice water. The air then goes through the hot [condenser] coil where it cools the hot refrigerant and reheats the air before being returned to the room.
If you have the patience to follow along the video, it explains the cycle.

The compressor and fan are running, however, there is no water coming out. RH is 70, temp is 66. This is after replacing a blower that had already seized up 2 years ago.

The dehumidifier should be removing water at 66F 70%rh.

First make sure that the compressor and fan are running. If they are, then turn the dehumidifier off and unplug the cord from the wall outlet. Next remove the front cover from the dehumidifier. Examine the evaporator coil (about 1/2 way up) beneath the plastic heat exchanger and above the stainless steel drain pan.

If the evaporator coil is cold and completely covered with frost & ice, the defrost thermostat may be defective. Replace the front cover. turn the humidity dial to "off". Plug the dehumidifier in to the wall outlet and set the fan switch to on - the fan will run (no compressor). Run this way for one hour to defrost the evaporator. Now adjust the humidity dial to your desired humidity and keep an eye on the dehumidifier. If it freezes up again and does not automatically defrost, the defrost thermostat should be replaced. Call the manufacturer at 1-800-533-7533 for parts and instructions.

If the evaporator coil is (mostly) warm and free of frost and ice, it is likely that some of the dehumidifier refrigerant has leaked out. this type of service should be done by a (refrigerant) certified technician. Call the manufacturer at 1-800-533-7533 for help with this service.

Model DE45EJ-L Fan works , does not take humidity out of the air

clean the dust off of the condenser in the front or the filter if it has one. no air flow results in overheating and no condensation across the evaporator coil.

I have the FAD704TDP 70 pint dehumidifier and it keeps freezing up right behind the filter. What steps would I take to keep it from freezing? Thanks

Blocked/poor airflow are the most likely culprit. Make sure the filter and evaporator are clean. If the evaporator is caked with dirt you can try carefully cleaning it with a wet rag and a shopvac. If they are both clean check to make sure the fan is blowing air across the coils. Final diagnosis would be a refrigeration issue.

Compressor stops at proper humidity % but the fan keeps running.

Dehumidifiers are built that way. They keep moving air so it is able to keep any change of conditions moving around the room. On a dehumidifier, it the fan stops, your unit will short cycle becasue water will naturally evaporate from the water tank and it would turn on, then off, then on then off. The way it runs now is fine. Running the fan 24 hours on your dehumidifier cost nickels a day. Just let run.

You could be overcharged or undercharged with refrigerant, a dirty condenser or evaporator coil or fan or blower motor not running at full speed, or you could have a dirty filter or or possibly a bad capacitor on the compressor.

No moisture

check to see if the coils in the back are cold. if they are not, you either have no freon or the vent in the front is blocked and the condenser coils have no air flow to cool down. if they are, there might not be sufficient air flow across the evaporator coils or the air is already dry.

also, if the bucket switch isn't activated (due to the bucket not being in all the way), the fans will come on, but not the compressor.
