Our old fridge was apparently leaking the refrigerant & it made me sick - I had come home after working & gone to sleep upstairs in our split level, not realizing the odd odor was the lighter-than-air refrigerant. I had to get up at noon & had a whopping headache when I did. Took a couple of aspirin & went back to bed & woke up to the alarm at 2:30. By the time I got up the headache was severe & my vision looked wavy, like when you look across a hot parking lot in 90+ degree heat. I ended up calling in sick to work, but when DH came home, he recognized it for a leak & after an hour outside of the house, the headache was backing off & I was feeling better.
DH & I decided to replace it with an energy star fridge from Sears, same size & type. Since the headache day, we have kept the windows open regardless of the weather. The fridge was just delivered today. I will sleep better tonight than I have for a week, & I am pleased to have the energy star appliance.
