Question Replaced an old t-stat recently with a new programmable t-stat (ritetemp model 6025). Initially had issues because person who installed or "jury rigged" the AC before us had used a non standardized color coding system on the wires.
Finally all was well. AC turns on fine but fan switch has to be on the ON position or no air blows through the vents. Turn on COOL and put fan on ON and everything seems to work fine. T-stat reaches target temperature and AC turns off but fan keeps going pulling in "hot" outside air (atleast I think it's outside air). Only way to turn off the fan is to put the fan switch to AUTO.
If AC is turned on to COOL and fan switch on AUTO, you can hear AC kick on but no air. (did i say this already?)
You can put the AC switch to OFF and leave fan switch to ON and fan keeps blowing warm air.
I have a Goodman AC model # PH036-1A and wires I've connected to T-stat are as follows:
Y on stat to Y on AC (yellow wire)
Rh bridged Rc to R on AC (red wire)
O on stat to O on AC (white even though it should be orange?)
G on stat to G on AC (green wire)
C on stat to C on AC (blue wire)
What did I do wrong?
By the way I live in hot hot Arizona so I don't really care for any heat.
Answer The O is not to be connected to O. Is this a heat pump ? Doesn't seem to be. The white is for heat, which is the W on the tstat. Blue wire is a sub for yellow wire to AC. The C wire may be black or brown for Common,not blue. The C wire is usually black or brown.
