Have HVAC Questions? Ask an HVAC Expert for Answers
hi i am dan. i can help you with this. i am not sure about that brand of thermostat but most of them when they are flashing like that it means it is in delay, wait 5 minutes and see if it starts after that
ok does the heat work?
ok do you have a gas furnace or a heat pump?
so it is a heat pump then as in the outdoor unit will run in heat and cooling correct?
ok first thing we will try is if you can remove the thermostat and on the back plate if you connect the R and Y wire together we will see if the outdoor unit starts
on the back plate where all the wires connect you can disconnect the R and Y wires and just twist them together or put a wire nut on them if you have one available
ok that may be best if you are not comfortable with disconnecting parts and testing. if you are concerned about power surges i would highly recommend having a surge protector installed in your electrical panel for the whole house or you can have one just for the A/C unit. if you have any more questions please let me know. if not i would appreciate if you could rate me on my service today and thank you for using just answer
