If you are experiencing main power problems with your ClimateMaster Heat Pump, and the Green Status LED is off, check the line voltage circuit breaker and disconnect. Check for line voltage between L1 and L2 on the contactor. Check for 24VAC between R and C on the CXM/DXM. Check the primary/secondary voltage on the transformer.
What to do if my ClimateMaster Heat Pump shows LT1 Fault Code 4 Water coil low temperature limit?
If your ClimateMaster Heat Pump displays the LT1 Fault Code 4, indicating a water coil low temperature limit, it could be due to several factors. Check for reduced or no water flow during heating by inspecting the pump and water valve operation. Clean or replace any plugged strainers or filters. Ensure the water flow is adjusted to the correct rate. Verify the antifreeze level using a hydrometer. If using antifreeze, ensure the JW3 jumper is clipped for the correct temperature limit setting (10°F [-12°C]). Confirm that the water temperature is within the specified design parameters. Check the temperature and impedance correlation using the provided chart.
Why does my ClimateMaster Tranquility 20 TSH 006 Heat Pump unit short cycle?
If your ClimateMaster Heat Pump is short cycling, start by checking the air filter and clean it if it’s dirty. Verify that the unit is not in 'test mode'; if it is, reset the power or wait 20 minutes for it to automatically exit. Also, the unit may be oversized for the space, so check the sizing against the actual load. Finally, inspect the compressor for any signs of overload and replace it if necessary.
What does LT2 Fault Code 5 Air coil low temperature limit mean for ClimateMaster Heat Pump?
If your ClimateMaster Heat Pump displays the LT2 Fault Code 5, indicating an air coil low temperature limit, it could be caused by several issues. Check for a dirty air filter and clean or replace it. Inspect the fan motor and check for any airflow restrictions. Also, check if the external static pressure is too high by comparing it to the blower table. Ensure the entering air temperature is within the design parameters, addressing any excessive cold vent air. Verify that the temperature limit setting is correct (typically 30°F [-1°C] for normal airside applications). Finally, check the temperature and impedance correlation using the provided chart.
Why does only the fan run on my ClimateMaster Heat Pump?
If your ClimateMaster Heat Pump fan is the only component running, ensure the thermostat is correctly set for heating or cooling operation. Check for any lockout codes and reset the power. Inspect the compressor overload and replace it if necessary. Verify the thermostat wiring at the heat pump, using a jumper between Y and R to test compressor operation in test mode.
How to fix Condensate Fault Code 6 on a ClimateMaster Tranquility 20 TSH 006?
If your ClimateMaster Heat Pump is showing the Condensate Fault Code 6, start by checking the drain for blockages and clean it. Inspect the trap dimensions and ensure it is located ahead of the vent. Verify that the piping slopes away from the unit to ensure proper drainage. Check the slope of the unit toward the outlet. Ensure proper venting by checking the vent location. Inspect for moisture shorting to the air coil. Replace the air filter. Find and eliminate any restrictions to the return air flow, and consider increasing the return duct and/or grille size.
What does LP/LOC Fault Code 3 Low Pressure / Loss of Charge mean for ClimateMaster Tranquility 20 TSH 006?
If your ClimateMaster Heat Pump is showing the LP/LOC Fault Code 3 indicating Low Pressure / Loss of Charge, check for refrigerant leaks. Also, check the charge and start-up water flow.
What causes Over/Under Voltage Code 7 (Auto resetting) on ClimateMaster Tranquility 20 TSH 006 Heat Pump?
If your ClimateMaster Heat Pump is showing the Over/Under Voltage Code 7, which auto resets, check the power supply and 24VAC voltage both before and during operation. Verify the power supply wire size. Check the compressor starting and consider whether a hard start kit is needed. Check the 24VAC and unit transformer tap for the correct power supply voltage. For over voltage, check the power supply voltage and 24VAC before and during operation. Also, check the 24VAC and unit transformer tap for the correct power supply voltage.
What does Unit Performance Sentinel Code 8 mean on ClimateMaster Tranquility 20 TSH 006 Heat Pump?
If your ClimateMaster Heat Pump shows the Unit Performance Sentinel Code 8, and it's in heating mode with LT2 exceeding 125°F [52°C], check for poor air flow or an overcharged unit. Also, check for poor water flow or air flow.
What to do if my ClimateMaster Tranquility 20 TSH 006 Heat Pump shows no fault code but the compressor won't work?
If your ClimateMaster Heat Pump is not showing any fault codes but there is no compressor operation, refer to the section on 'Only Fan Operates'. If there is a compressor overload, check and replace the compressor if necessary. If the issue is with the control board, reset the power and check operation.
