My 2nd dehumidifier over 27 yrs. Never cleaned coils once before today. But did so today. Made no difference and hardly anything on them. The first 5 coils ice up within 5 minutes. Then it moves gradually into the 9th of 20 coils and continues to thicken up the ice. Fan is running fine as is the compressor. Air path is clear - especially with front screen and rear air filter removed. A tiny bit of dust in the condenser fins but it can't be the cause of the unit going rogue in one day. Never seen ice before during mid-summer.
Looks like time to look for a new unit...as this must be losing Freon. Any recommendations for a new 900 sq ft basement unit? I think my last one cost around $225. I run it mostly from late May to early September.
I just need something simple as I empty my 2 gallon tub manually once or twice a day. No need for level control, timers or other such things. Just a humidistat dial and a fan speed selection.
If you really feel you don;t need a new dehumidifier, then read this below.....
You either live in a low spot - water your front & back lawn too much - have mortar cracks on your outside walls - have home windows that need caulk badly - no cinder block basement windows....... something is going on, that it can't keep up with a sub-1000sq ft basement/home.
I have a Home Depot-purchased, money-value three feet high Danby Silhouette dehumidifier that's now about 6-7 years old and like you, a 1000 sq ft basement/home. Mine worked hard until I sealed the entire outside last fall, both windows and cracked mortar. Then I put five cinder block windows over my existing basement windows. - mortared them nice & tight.
My dehumidifier has never reached 60% humidity yet this summer. I live right-smack in the middle of the Great Lakes region and I water my yards constantly. My humidity level this summer has stayed close to 50%, a first-time in the 35 years I lived here.
Either buy another dehumidifier or seal everything real good outdoors.
