Sub-Zero repair in Walpole

Sub-Zero built these to be serviced, and a cabinet of that age is usually still worth servicing. Fan motors, defrost heaters, thermistors, gaskets, hinges and even most control boards are replaceable, and the case, the insulation and the joinery around it are all fine. Replacing the appliance means replacing the cabinetry it is trimmed into as well, which is the part that makes the sums so lopsided.

What changes the answer is the sealed system. A compressor or a refrigerant leak in a unit that also has a tired fan and a board that has been reset twice is a different proposition, and pretending otherwise costs the owner more than being told plainly.

• Which component failed, and whether it is serviced or replaced
• What else is measurably close to failing on the same visit
• Whether the part is current production or has to be sourced
• What replacing the unit would cost once panels and cabinetry are counted

The bands below are what the repairs themselves run to. Set against them is the cost of a replacement, and the appliance is only the first part of that: delivery, installation and the joinery work a built-in swap drags with it all follow. That is why a serviceable fault on a sound cabinet is nearly always the better spend.

A condenser coil brushed and vacuumed a couple of times a year is the single most useful thing an owner can do for a built-in, and it is free. A coil packed with dust makes the compressor run longer and hotter for the same result, which is how a unit that would have run for twenty-five years stops at eighteen.
