      If your Hephzibah Heat Pump isn't working, several factors could be the cause. Start by ensuring the power cable is correctly connected. If it is not, connect it correctly. Check if the power button is in the "OFF" position and press it to "ON". Examine the fuse in the board and exchange it if blown. Also, verify if the breaker on the switchboard has tripped, and if so, check the load capacity and reset it. Finally, confirm that the ambient temperature is within the operating temperature range.

      Poor cooling in your Hephzibah Heat Pump can be due to a few reasons. The filter might be blocked with dust, so you should clean it. There could also be dust in the heat exchanger, requiring you to clean the heat exchanger. Another possibility is an obstacle against the inlet side; remove any obstructions and ensure a 20"(50cm) clearance.
