Why is my Bosch SM060 Heat Pump not cooling or heating enough?
- C
  catherinetownsendAug 17, 2025
  Insufficient cooling or heating in your Bosch Heat Pump can stem from several causes. The unit might be undersized, requiring recalculation of heating/cooling loads, possibly with added insulation. Leaks in ductwork or ambient air entering through doors/windows could cause loss of conditioned air. Inadequate airflow, often due to a dirty filter, can also be a factor. A low refrigerant charge leads to inefficient operation. Other potential issues include a defective compressor or reversing valve, restrictions or defects in the TXV, or contamination of the refrigerant system with moisture or non-condensables. Compare the unit's operating pressures to the pressure/temperature chart to diagnose the issue.

What to do if my Bosch SM060 is not running at all?

  If your Bosch Heat Pump isn't running, start by checking the power supply. Ensure the disconnect is closed and power is applied. Inspect for blown fuses or tripped breakers, replacing or resetting them as necessary, ensuring correct fuse size. Verify the voltage supply meets the unit's data plate specifications; if it's low, contact your local power company. Also, examine the thermostat. Set the fan to 'ON' to see if the fan runs. Test 'COOL' and 'HEAT' modes with extreme temperature settings to check for proper operation. If issues persist, confirm 24 volts at the low-voltage terminal strip between 'R' and 'C,' 'Y' and 'C,' and 'O' and 'C,' and between 'G' and 'C' in the air handler. Replace the thermostat if it's defective.

Why does my Bosch SM060 turn off due to high pressure?
- A
  Amy KirkAug 26, 2025
  Your Bosch Heat Pump might be shutting down due to high pressure for a few reasons. In 'COOLING' mode, check for insufficient water flow, excessively warm entering water temperature, or a scaled/plugged condenser. In 'HEATING' mode, ensure adequate fluid flow on the load side, and verify the blower is operational, the filter isn't clogged, and ductwork isn't restricted. An overcharged refrigerant level can also cause this issue; in that case, reclaim refrigerant, evacuate, and recharge to the factory-recommended level. Finally, inspect the high-pressure switch for defects or improper calibration.

What causes a Bosch Heat Pump to shut off due to low pressure?
- S
  Stephanie OliverAug 28, 2025
  A Bosch Heat Pump shutting off due to low pressure can be attributed to several factors. In 'COOLING' mode, investigate potential issues such as insufficient airflow, excessively cold entering air temperature, a non-operational blower, a clogged filter, or ductwork restrictions. If in 'HEATING' mode, check for inadequate water flow, excessively cold entering water temperature, or a scaled/plugged condenser. A low refrigerant charge is another possibility; look for refrigerant leaks, repair them, evacuate the system, and recharge with the factory-recommended amount. Lastly, examine the low-pressure switch for any defects or calibration problems.

How to fix a Bosch Heat Pump that short cycles?
- J
  Juan JonesAug 31, 2025
  If your Bosch Heat Pump is short cycling, several factors could be responsible. The unit might be oversized, requiring recalculation of heating or cooling loads. The thermostat's location could be the problem if it's near a supply air grill; try relocating it and adjusting the heat anticipator. Also, check the wiring and controls, specifically looking for a defective or improperly calibrated low-pressure switch.

What to do if my Bosch Air Handler unit is off due to high-pressure control?
- J
  John PriceSep 5, 2025
  If your Bosch Air Handler shuts off due to high-pressure control, consider these potential causes: * **High Discharge Pressure:** If in 'COOLING' mode, check for lack of or inadequate water flow, excessively warm entering water temperature, or a scaled/plugged condenser. If in 'HEATING' mode, check for lack of or inadequate load-side fluid flow, an inoperative blower, a clogged filter, or ductwork restrictions. * **Refrigerant Overcharge:** The unit may be overcharged with refrigerant. If this is the case, reclaim refrigerant, evacuate, and recharge with the factory-recommended charge. * **High-Pressure Switch:** Inspect the high-pressure switch for defects or improper calibration.

  Marcus DuarteSep 12, 2025
  If your Bosch Air Handler is short cycling, here are some things to check: * **Unit Size:** The unit might be oversized. Recalculate the heating and/or cooling loads. * **Thermostat Placement:** If the thermostat is near a supply air grill, relocate it. Also, adjust the heat anticipator. * **Wiring and Controls:** Check for a defective or improperly calibrated low-pressure switch.
