When the repair is not a close call
Of the 6 bands published on this site, 3 land under a fifth of the
cheapest machine they could be fitted into, and most of those land under a tenth:
igniter or burner assembly, oven thermostat or heating element, refrigeration fan or defrost system. At those proportions the rule
of thumb is not being applied, it is being ignored, and rightly. A working machine with one
failed part is worth the part.
This is the bulk of the work at the beach, and it is not an accident. Exposure takes the
cheap things first — a burner cap and its electrode, a condenser fan, a defrost heater, a
pump seal — long before it reaches anything expensive. What is worth arguing about is not
whether to fix it but whether the cause is still in the house, because a part fitted into
an unfixed cause is the same repair bought twice.
When it is a judgement call
Between a fifth and half sit dishwasher pump or control at 46% and compressor or sealed-system repair at 28%. Both are still under the line, and both are where the reflex answer is most often
wrong — in opposite directions.
A sealed-system failure sounds terminal and reads as terminal, and on a built-in it is
nothing of the sort: the cabinet it sits in is the most expensive thing in the kitchen, so
even the dearest repair in this book is a fraction of replacing it. The dishwasher runs the
other way. Its repair band is modest and the machine it sits in is the cheapest one here, so
the same sum that clears a compressor comfortably brings a pump close to the line.
What tips either of them over is not the price of the one repair, it is the second one. An
appliance that has already had a board, or has water damage in more than one housing, or is
showing corrosion where the repair cannot reach, is a different arithmetic — and it is
explained at the kitchen table, on the written estimate, not asserted here.
When the rule actually fires
One band does cross it: control board or touch panel, $410–$1,010, measured in the cheapest machine it can sit in — a built-in dishwasher starting at $1,600 — which puts it at 63% at worst. The dishwasher is the honest exception on this equipment, and it is the one place where
the rule everyone arrives with does real work. A machine that needs its control as well as
its pump has spent most of a new one, and you will be told that on the estimate rather than
sold the repair.
There is one more case the tables cannot show, because it is not a repair at all: a cracked
cooking surface, a split cabinet liner, a burnt-out mains connection inside a housing that
has corroded through. Those are replacements wearing a repair's clothes, and the honest
answer to them is given on the telephone rather than after the
$80 visit.
How long should it have lasted?
The question behind the question, usually. There is no figure published here for it, because
this shop has not measured one and a number invented for a web page is worth nothing. What
the trade generally observes is that professional cooking equipment outlives the kitchen it
was fitted into, and that sealed refrigeration is the part of a built-in that sets the end
of its life rather than the cabinet or the doors.
On this coast the variable that moves it most is not age and not use. It is exposure —
which is why the equipment three blocks from the Atlantic and the identical equipment four
miles inland do not have the same working life, and why the
field notes on this site keep coming back to it.
