When a built-in is worth repairing, and when it is not
Replacing a built-in means replacing the opening it lives in as often as not. That changes the arithmetic, and it is why the honest answer is rarely a single number.
With a free-standing appliance the repair-or-replace question is close to arithmetic. The repair costs what it costs, a new machine costs what it costs, and the old one leaves on a trolley. A built-in is a different question, because the appliance and the kitchen are one object.
The rule people arrive with
Most callers have heard some version of the fifty per cent rule: if the repair comes to more than half the price of a new machine, replace it instead. On a free-standing appliance that is a decent shortcut. On a built-in it fails at the denominator, because the price of “a new machine” is not the price of the appliance. It is the appliance plus whatever the opening, the panel and the vent path have to become in order to accept it.
Keep the rule as a direction of travel, then, rather than as a threshold. The two tables at the foot of this page are the halves you need to do it properly: what the repairs themselves band at, and what a like-for-like appliance costs before anybody touches the joinery.
The cabinet is part of the price
A built-in lives in an opening that was cut for it, and the run of joinery either side was finished to that opening. Replacing the appliance means finding a new one that fits the opening in all three dimensions, matches the way the old one vented, and lands its hinges and its handle where the previous machine left its marks.
Sometimes that is easy. Sometimes the modern equivalent is a fraction different in a direction that matters, and the honest quote for a replacement includes a cabinetmaker. A panelled installation adds another layer, because the decorative front was made for the old door and its fixing pattern is unlikely to be repeated.
None of that argues for repairing everything forever. It argues for knowing the full number on both sides before choosing, which is why we measure the opening as well as the appliance when a repair starts to look marginal.
Doing the sum with the two tables below
Three outcomes, and most calls land in the first.
Clearly worth repairing. Igniters and surface elements, oven sensors and thermostats, bake and broil elements, convection fans, hinges and door seals. Every one of those bands is in the hundreds, set against a replacement table that starts in the thousands and stops at the appliance — before delivery, before installation, before a cabinetmaker is called. There is no arithmetic to agonise over here, and we do not pretend there is.
A judgement call. Two bands climb into four figures: a control board or touch panel, and the sealed system on a refrigeration column. Even at the very top of its band the sealed-system repair comes in under the lowest replacement figure in the second table, so on the money alone the repair still wins. Money is not the only term. What tips it the other way is a part no longer made for your serial, a second fault already showing on the same machine, or a suite that went in during one month and is now reaching the same age together.
Not worth it. When two of the larger repairs land on one appliance at once, when the component simply cannot be had, or when the fault belongs to the installation rather than to the machine. That last one is worth saying twice: a restricted grille, a duct that never worked or a circuit carrying more than it was drawn for is inherited whole by a new appliance, at full price, with the cabinetry bill on top.
What actually decides it
Four things, in roughly this order.
What failed. A door seal, a hinge, a switch, a fan, a pump or a control board are all ordinary repairs on an appliance that is otherwise sound. A sealed system fault on a refrigeration appliance is the one that genuinely changes the calculation, because it is the most expensive repair on the machine and the one most sensitive to the appliance’s age.
How the rest of it looks. We are inside the machine anyway. Corrosion, a condenser that has been running restricted for years, a cabinet that has been worked on repeatedly, or evidence of water where water should not be all suggest the next fault is not far behind.
Whether the part exists. A repair is only a repair if the component can be had. Functional parts usually outlive cosmetic ones by years.
What else is the same age. In kitchens where the whole suite went in during one month, the second fault often arrives within a year of the first. That is not a reason to panic, but it is a reason to plan the room rather than repair it one item at a time.
Where we will tell you not to bother
We will say plainly when a repair is a poor investment, and we will put the reasoning in writing so you can weigh it without us in the room. A quote that approaches a meaningful share of a like-for-like replacement, on an appliance old enough that the next failure is a question of when rather than whether, is a repair we would not make on our own kitchen.
The same applies in the other direction. Where a fault is being blamed on the appliance and belongs to the installation — a restricted grille, a duct that never worked, a circuit carrying more than it was drawn for — replacing the appliance solves nothing and costs a great deal. We would rather lose the sale than watch a new machine inherit the same fault.
The one thing worth doing early
Ask the question before the appliance is dead. A diagnosis on a machine that is still limping gives you options and a timetable. The same diagnosis after a failure gives you a decision to make in a hurry, usually with the contents of the appliance sitting in a cooler on the kitchen floor.
The flat diagnostic covers the visit and the diagnosis, it is credited toward the repair when you approve the work, and the findings come to you in writing either way. The figure itself is on the card beside this note and at the head of the table below it.
Before the estimate
What does a repair cost once the diagnostic is done?
The visit is a flat $80 and it comes off the repair once you approve it. What the repair itself lands at depends on the part, and these are the bands the work below has actually fallen into. A band is not a quote: the firm figure is written down after the appliance has been opened and measured.
| Repair | Typical range |
|---|---|
| Diagnostic visit | $80 flat, credited |
| Igniter, spark module or surface element | $210–$530 |
| Oven thermostat or temperature sensor | $170–$560 |
| Bake or broil element | $200–$570 |
| Convection fan or motor | $250–$660 |
| Control board or touch panel | $430–$1,100 |
| Door hinge, glass or seal | $200–$650 |
| Refrigeration column sealed system | $880–$2,300 |
When is replacing the cheaper answer?
A comparable Thermador wall oven, rangetop or column, appliance only — before delivery, installation or cabinetry. National appliance pricing, not Florida labour. Hold the band above against the figures below before you decide, and remember that a built-in also has to fit the opening it came out of.
| Instead of repairing | Appliance cost |
|---|---|
| Wall oven, the usual repair-or-replace comparison | $4,200–$9,500 |
| Professional rangetop or range | $5,500–$14,500 |
Follow-up questions
What do people ask after reading this?
- What is the 50% rule, and does it hold for a built-in?
- The rule says replace once the repair passes half the price of a new machine. It works on a free-standing appliance. On a built-in the denominator is wrong, because replacing also means matching an opening, a vent path and a panel, so the cabinet belongs in the sum.
- Is a twenty-year-old built-in worth repairing?
- Age on its own decides nothing. What decides it is whether the part is still made for your serial, whether the fault belongs to the appliance or to the installation around it, and what else in the kitchen went in the same month. All three are answered on the visit.
- Is a sealed-system repair on a column worth doing?
- That work runs $880–$2,300. The replacement figures on this page start at $4,200 for the appliance alone, before delivery, installation or cabinetry, so the repair is the cheaper half even at the top of its band. Age and a second fault already showing are what change that.
- Why is there no single number for repair or replace?
- Because replacing a built-in often means replacing the opening it lives in. The appliance is only part of the price, and cabinetry, panels and electrical work land on the other side of the comparison. The band table below is the honest half we can publish.
- What actually decides it?
- Whether the part is still made for your serial, whether the fault is the appliance or the installation, and what the cabinet would cost to change. A restricted grille or a duct that was never right belongs to the kitchen, and a new appliance inherits it.
- When will you tell me not to bother?
- When the sensible answer is that the appliance is not worth the part, we say it during the diagnostic visit. You will have paid for the visit to find that out rather than several times more to find it out afterwards, and you keep the findings.
The line we work to
Where the work stops
We work on the built-in appliances inside the kitchen and nothing else. The only duct we open is the one above the cooking surface, from the hood to the wall cap outside — the supply and return ducts that heat and cool the house are a different trade altogether and we are not in it. If the call is about a furnace, an air conditioner, an air handler or a vent in the ceiling, we will say so on the phone and send you elsewhere rather than book a visit.
A call from Mandarin about a Thermador appliance is ours. A call from Mandarin about the furnace, the air conditioning or a vent in the ceiling is not, and we would rather tell you that in thirty seconds on (904) 201-3304 than on your doorstep.
