found outside tripped outside breaker and when turned back on the compressor and fan engaged, immediate cool air.
However, we still see cool 2 on screen vs just cool as usual for manual set
how to get back to cool from cool 2
unit is 18 months old, just had AC serviced including fin leaf and dirt flush, this is a top of the line unit which hit all factory specs on service checkout, we had a 105 degree day here in Austin and been above 100 for the past week with more coming for the next 4-6 weeks.
We are back to just cool this morning. What are your thoughts on the nest learning thermostat?
what do you call this protective device and what risk do we have of voiding a manufacturers warranty if we put it in a system still covered by warranty?
Regarding the " voltage monitor and cut off" I mentioned, You can fit that into the unit if done properly without voiding the warranty in most cases. However this should be purchased locally, at an air conditioning and refrigeration wholesaler by the service people so that it can be properly selected and wired.
A home owner can make mistakes...or.... anyone seeking to void your warranty can use that as excuse to void your warranty. So it should be done professionally.
If your service contractor is not familiar with these devices you need another service contractor who is up to speed on these issues...
You can also buy a class 2 multi meter (with a 240 volt scale on it) cost about $30 and use it to check the voltage at the disconnect switch on the wall next to the condensing unit **during the time it starts on a very hot day** tell me how low the voltage dips during that attempted start attempt.. and what the voltage reads after the unit is running.. compare that voltage read to the voltage listed on the name plate of the unit.
Let me know the results, we can go from there if you have already rated my responses *positively. I hold questions open with no time limit in those cases.
