Question about Heating & Cooling
You probably have a plugged condensate drain line, you will need to clear that out. It may be that the coil is also icing up. That could be due to a plugged air filter or a low refrigerant charge in the system.

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!

Wish there was more that I could do to help but you may need to have someone or yourself check for anything shorted/grounded and also make sure the voltage is correct to the solenoid.

You must have too many things running on that circuit. Check your connection to the power box.Loose connection on the receptacle can cause the breaker to trip or too many things running on the same circuit. If the breaker is old it might need to be replaced.

i have nothing on my thermostat. I was going to install a programable thermostat so I disconnect my old one. When I couldn't use the new one I reinstalled the old one and now it's like there is no power to it. Checked circuit breakers and found none tripped and tried thermostat in upstairs since I have two thermostats and it works fine there What next???
