Frost My Gold Star Dehumidifer frosts up after start up. I have turned on and off may times over many days. Spend today turning off many times to let frost melt off. Frost covers 1/2 of coil then stays. Coil and filter is clean. Plenty of room for air movement. Fan working on high. Unit is 7 years old.

its low on refrigerant if you mean the refrigerant lines have frost on them,sometimes if you use them in to cool of an area with lots of humidity they will do this too

According to your Owners Manual, the coils may start to frost at 60 degrees and the defrost sensor should turn ON and cycle periodically. However, the air temperature at the floor level in a basement, is colder than the air temperature by 5 to 8 degrees. So this may be causing the problem. In addition, if the air intake filter is dirty or clogged, the unit has to strain to keep up and will not function as it should.

If the unit is totally iced up, turn the unit Off and unplug it from the wall outlet. Allow is to thaw completely before attempting to clean the filter. You may want to put some old towels under it while it thaws. Once it's thawed, move it to a bathroom that has a shower. Plug it it in and set the humidity level at 45%. Turn the shower ON at a Medium hot temperature (enough to generate steam) and as you exit the batroom, close the door. DO NOT operate the bathroom's exhaust fan. Allow the unit to operate for 15 to 20 minutes, before returning to the bathroom. Then turn the shower OFF and check the unit for any frost and the amount of water collected in the bucket. If there is no frost on the unit and there's water in the bucket the unit is operating properly.

When you move it back to the basement, place it up off the floor on something sturdy, that can hold the weight and not be bothered by the vibration of the unit, when it's running. (ie a work bench, a counter top, etc.) Operate the unit as you normally do and monitor it for frost or icing up. And, whether or not the defrost sensor is cycling as it should. If you get no frost or just minor frost, it was the air temperature at the floor level, that was causing the problem.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

sounds like your evaporator coil is dirty its the coil where the air goes in

If you can remove cabinet, check glass fuse on power supply board.

After that it is probably the power supply board or the control board - see a service department

My dehumidifer is 6 years old. I lost my instructions. Do not know how to set for normal control.

Thank you.

My emerson dehumidifer Hd14070 has to containers only one works

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.

sounds like a sealed system issue it has a 5 yr. warrenty on the sealed system, cost to repair might mean an new one instead

expected? of course! this is not ur solution try draining all the water to the sewerage if u cant try to pump it out with a vacuum cleaner (that can pump water) or a pump then turn on the Dehumidifier every time it frosts turn it off untill it defrosts or u can heat up the basement with a bellower and the Dehumidifier wont frost
