1999 Monoco WINDSOR new AC and old AC issues

[themoneypit]

My air conditioners work for a few hours then both just quit putting out cold air. It is a minimal cold. what is going on is it an electrical problem.The front has never really put out cold air and it is new. The old one worked really well and now it is putting out cold air 1/2 day then almost warm air. help me. the control panel in the front shows no lights on the battery section. Has anyone else had this issue?

For starters would check AC units to see if they were icing up. This can be done by looking in thru the cover ventilation slots with a flashlight. Would also check for any dirty air filters and the units coils

May be the 12v fuse not making good contact to the control center, on our Dyn it is in the bedroom closet, I will past the reset procedure also.

For 5 button reset:

SYSTEM RESET
1. Turn the ON/OFF switch to OFF position.
2. Simultaneously depress and hold the MODE and ZONE push-buttons while turning the ON/OFF switch to ON. FF should appear in the LCD display until the MODE and ZONE push-buttons are released.
3. When a dip switch in the system control board is turned ON or OFF after initial configuration, a system reset will need to be done before the Comfort Control Center will recognize the updated selection. See figure 11.

For 4 button reset:

a. Turn the ON/OFF switch to ON. The display light with
data should come on. If the light and data are not there,
see Section B2 Cable Assembly.
b. Depress mode to activate display light.
c. Depress the bottom two buttons (up & down) together.
d. While still holding the two buttons add the third from the
bottom (mode) , hold all three for a few seconds.
e. Release the third (mode) button.
f. Release the bottom two (up & down) together.
g. Depress the mode button. The display light should be
off. If not, repeat steps 2 through 6.
The control should return to the default setting of 68oF for
heating mode and 72oF for cooling mode.

One other thing you might try is double check the 12v wires or control wires (look like telephone wires) under the AC where the filter is, re tighten the wire nuts.
