How To Recharge A Refrigerator? It is a dreadful frame of mind that consumes you if your reefer does not deliver the merchandise. It has been proven to paralyze cruisers for months on end, trapping them in exotic ports while waiting for this rare, elusive creature called a marine refrigeration tech.
I endured it for a brief time, once I inadvertently discharged the refrigerant in the new refrigerator unit I’d installed. A few months later, after having been let down by none but two distinct professionals and enduring a summer of needing to bag heavy coolers on board the first thing I had hoped to prevent installing a refrigerator, I decided it was time to find the courage and take action myself.
Reading various treatises on marine pipes just raised my angst. Different specialists on internet forums warned direly of the hazards of getting air to the system, failing to purge the pipes gauges, overcharging with refrigerant, and blinding oneself with speeding gases.
On the flip side, I understood that topping up the cost at a car’s AC system is an easy DIY job that the refrigerant and hoses are easily obtainable in auto-supply shops. Indeed, if any doofus can top a car’s AC system, any doors should be able to top up a marine refrigerator? It was time to learn.
It helped that I understood why my refrigerator had a charge: shortly after installing the Isotherm refrigerator unit, I’d undone among those Danfoss BD35 compressor quick-fit couplings to create space for the galley sink drain hose, also discovered that a different hiss as the gasoline produced good it escapes.
Had there been an unknown leak, the fix would have entailed tracing and fixing it, then sucking air and moisture from the machine using a vacuum pump before recharging. Probably, this might have required assistance from a few of these evasive professionals.

How To Recharge A Refrigerator?
- Step 1
Remove all of the foods from the fridge. Unplug the fridge and, if at all possible, move it to the middle of this space.
- Step 2
Find the fridge compressor. This really is a cylindrical black element typically found in the base of the refrigerator.
- Step 3
Open the compressor intake valve and then attach your vacuum to the valve that is opened.
- Step 4
Vacuum out the rest of the freon. It’s crucial to eliminate any residual freon to don’t overfill the compressor and threat leaking freon to the fridge or area where it’s kept.
- Step 5
Attach the hose out of the freon tubing to the valve. Tighten the attachment using a wrench before draining the freon to the compressor. Once emptied, shut the compressor’s valve.
The Way to Recharge Freon to Fix a Refrigerator
Freon, DuPont’s trademarked title for CFC and HCFC refrigerants, has come to be a generic title for several refrigerants. Refrigerators manufactured before 1995 generally comprised R-12, a CFC, as a refrigerant. Just EPA certified technicians can purchase R-12. Refrigerators made from 1995 to the current typically utilize R-134a, an HFC, as a refrigerant.
Both automobiles and cars utilize R-134a for refrigerants, and adults may purchase it at most auto parts shops. Mixing the noncompatible refrigerants R-12 and R134a will lock the compressor.
- Step 1
Eliminate the breaker access cover in the back of the fridge. Use a Phillips screwdriver along with a nut driver to remove the screws.
- Step 2
Examine the tag located on the compressor for the sort of equipment used.
- Step 3
Put in a saddle valve onto the massive copper pipe coming from the breaker. A saddle valve pierces the refrigerant line for accessibility. A saddle valve utilizes two bits to wrap around the tube using hex-head screws holding them together. Utilize the hex-head wrench that includes the valve assembly to tighten the hex-head screws.
- Step 4
Put in a refrigerant valve adapter into the saddle valve. The adapter screws on the saddle valve support interface.
- Step 5
Join a refrigerant charging hose kit into your can of refrigerant. The charging hose kit involves a color-coded gauge, hose, threaded fitting, which connects to the can of refrigerant, and a service valve link, connecting the adapter onto the saddle valve.
- Step 6
Connect the charging hose link to the saddle valve. This snaps into position.
- Step 7
Utilize the hex-head wrench to turn the piercing valve, located in the middle of the top half of this saddle valve, with three complete turns. Back out the wrench one complete turn. The residual refrigerant in the refrigerator ought to input the charging hose.
- Step 8
Turn on the fridge. Let it run until the strain gauge stops falling. This typically requires three to five minutes.
- Step 9
Check the pressure gauge. R-134a ideally must have between 25 and 45 psi. Open the refrigerant may interface, allowing refrigerant to join the system. Close to the vent each moment to examine the pressure. Continue to include refrigerant before the stress has reached the right selection.

- Step 10
Close to the piercing valve together with a hex-head wrench. Disconnect the charging hose. Reinstall the compressor accessibility cover.
