Humidifier in basement freezes up after several hours, ie coils are one big ice block.
I have put it on a timer with 4 hours on 4 hours off. Seems to work OK.
What causes this problem and is there a way to fix the unit itself?

- Thanks for the replys.I already checked and the unit is not clogged, it's actually pretty clean whoch was a surprise.
I originally suspected the basement was too cold, it's usually about 60 (+/- 5), but no one expersseed that as a concern.
Assuming it is low refrigerant, I have some R12 (from by-gone days and gagues. Do these units R12 and what would be the upper and lower pressures to charge to?

Hi there, Yes this problem has been asked before by other users,
Firstly, there are several things to look for be you go crazy calling in a technician,
1. check the systems coils and make sure that they are not blocked with either , dirt or dust preventing the air flow or make sure the condenser fan is operating ,if both these things are clear or operating when the compressor starts then the system could be under charged or leaking in which case a technician would be advisable unless you understand and or have the necessary tools to carry out its repair. The only other thing that could be causing it is , if the humidi-thermostat is faulty and is causing to stay on too long (with could be why the system appears to work properly if you turn it off once and a while )
I hope this information helps you..
Also, Please remember if you feel like opening the machine up to check the can if its not running, make sure that the machine is totally un-plugged from the power supply to prevent any chance of electric shock , please be safe :)
Thanks

- Hi , Yes if thats 60 Dg Fahrenheit (15.5 C) it can be a problem cause of the lack of heat the humidifier will be over condensing which will cause that too , (wish you would of mentioned that ) , best thing is to ventilate the area or move the system,Thanks

Problem could be caused by lack of air flow (dirty coils and/or filter) or by low refrigerant (not worth repairing).

- The unit rating plate should list the type of refrigerant. No, it's probably not R12. It probably does not have access ports. The pressures will vary due to ambient, and refrigerant. It is probably not worth having it repaired especially since any repairs would probably be temporary at best. I think you've already found the best solution/fix.Yes
No
