What to do if the compressor does not operate on Honeywell Accessories?
If the compressor on your Honeywell Accessories unit isn't running even when all other conditions appear correct, first, check the wiring from terminal {2} to Y1 on the unit's low voltage control board. Also, verify that there are not 24 Vac to Y1 and C on the unit.
What to do if the compressor does not operate with second stage conditions met on Honeywell Accessories?
If the compressor on your Honeywell Accessories unit isn't running even when the second stage conditions are met, check the wiring from {5} to Y2 on the unit low voltage terminal board, assuming all other functions are working correctly.
How to troubleshoot a motor that doesn't operate on Honeywell Accessories?
If the motor of your Honeywell Accessories unit isn't working even when all conditions are met: * Jumper the mixed air sensor terminals {T} and {T1}. * If the motor starts, check the wiring to the sensor. If the wiring is correct, the temperature might be below the sensor's setpoint, or the sensor could be defective. * If the motor still doesn't operate, and the wiring is correct with the temperature above the sensor setpoint, the motor itself might be faulty.
What to do if the motor does not operate with all above conditions met on Honeywell Accessories?
If the motor of your Honeywell Accessories unit isn't working even when all conditions are met: * Jumper the mixed air sensor terminals {6} and {D}. * If the motor starts, check the wiring to the sensor. If the wiring is correct, the temperature might be below the sensor's setpoint, or the sensor could be defective. * If the motor still doesn't operate, the wiring is correct, and the temperature is above the sensor setpoint, the motor itself might be faulty.
Why is there no 24 Vac to terminals {TR} and {TR1} on Honeywell Accessories?
To troubleshoot a lack of 24 Vac to terminals {TR} and {TR1} on your Honeywell Accessories unit, check the wiring from [G] and [C] on the unit's low voltage terminal strip. Note that {TR} and {TR1} power the actuator.
What to do if there is no 24 Vac to terminals {1} and {TR1} on Honeywell Accessories?
To troubleshoot a lack of 24 Vac to terminals {1} and {TR1} on your Honeywell Accessories unit, verify that there is a call for cooling from the thermostat. Without a call for cooling, the compressor cannot be in the normal air conditioning mode.
