- 1). Switch your air conditioner off for 24 hours and allow the unit time to effectively defrost. This is inconvenient as you will be without air conditioning for a day but it is an effective cure to the problem.
- 2). Check the unit is completely free of moisture after 24 hours. There should be no standing water around the unit, and you should use a dry cloth to mop up any condensation which may have built up.
- 3). Add coolant to your air conditioner before switching it back on. You can buy air conditioner coolant at most hardware stores, and the product will come with instructions regarding how to top up most major models of air conditioning units. If you are uncomfortable, then ask an expert to top up your air conditioning unit.
- 4). Switch the breaker switches for your air conditioning unit back on, before turning the unit to "Fan" at the control box. Verify that the fan is indeed working again, before selecting "Low Cool" to allow the unit to operate normally once more.
