Turn on the internal water pump for ten minutes to completely saturate the cooling pads before turning on the fan. Let s start with the easy things first. If this doesn t resolve the issue it may be time to replace the pump. But there may be issues with placement leakage or supply that prevent that.

If it is 95 degrees out that is what you are going to have inside your home.
