Finding the Refrigerant
Figuring out the kind of refrigerant utilized in your fridge is essential earlier than making an attempt a recharge. This info might be present in a number of places.
| Location | Particulars |
|---|---|
| Fridge’s information plate | Normally positioned contained in the fridge door, this plate supplies the mannequin quantity, serial quantity, and refrigerant sort. |
| Fridge’s proprietor’s guide | In case you nonetheless have the guide, it should additionally specify the refrigerant used. |
| Refrigerant label on the compressor | The compressor is normally positioned on the again or backside of the fridge. Search for a label with the refrigerant’s identify and specs. |
After getting positioned the refrigerant info, it is essential to notice that recharging a fridge ought to solely be tried by a certified technician. Refrigerants are hazardous supplies and improper dealing with can pose important dangers.
Shelling out the Refrigerant
**Step 1: Join the Charging Hose to the Refrigerant Tank**
Find the charging hose and join one finish to the refrigerant tank. The opposite finish of the hose shall be used to connect with the low-pressure port on the fridge.
**Step 2: Purge the Charging Hose**
Open the valve on the refrigerant tank barely to purge any air or moisture from the charging hose. Maintain a rag or material over the hose finish to stop any escaping refrigerant.
**Step 3: Join the Charging Hose to the Fridge**
Find the low-pressure port on the fridge. It’s sometimes positioned close to the compressor and has a smaller diameter than the high-pressure port. Join the charging hose to the low-pressure port by screwing it on tightly.
**Step 4: Open the Valve on the Refrigerant Tank**
Slowly open the valve on the refrigerant tank to permit the refrigerant to circulate into the fridge. Monitor the strain gauge on the refrigerant tank to make sure that you don’t overfill the system. The goal strain for many fridges is between 5 and 15 psi.
**Step 5: Shut the Valve on the Refrigerant Tank**
As soon as the specified strain has been reached, shut the valve on the refrigerant tank to cease the circulate of refrigerant. Disconnect the charging hose from the fridge.
| Step | Motion |
|---|---|
