well the old one was thrown away. so it's not around to be re-installed. it's just surprising how two brand new thermostat rated at 87 would not function properly. I agree with the theory where it should "start" to open at 87. what should i tell the dealer ? to replace it with a different one ? i don't want them arguing with me that's all.
