Common fault
What is the loud humming or rattling from my refrigerator?
Short answer
A new noise from a built-in almost always comes from behind the grille rather than from inside the cabinet.
Why we start there
The condenser fan is the usual source: it rattles when it picks up debris and it whines when the bearing starts to go, and inland it runs far more hours per summer than the same fan does on the coast. Compressor mounts harden with age and hum through the cabinetry, which is annoying rather than urgent. The reason not to wait is that a fan left to seize stops the unit rejecting heat, and at that point it is no longer a fan repair.
What happens next
Describe the noise with two details and we can usually name it before we arrive. First, where it is coming from: top grille, bottom grille, or inside the box. Second, whether it is constant or comes and goes with the cooling cycle. A rattle that appears for a minute and stops is a fan blade touching something. A steady drone that has grown louder over months is a bearing or a set of mounts.
Dust and grit are why this comes up more often here. A condenser fan that spends its life pulling air off a decomposed granite driveway wears its bearing faster than one in a sealed suburban kitchen, and anything the fan draws in, insulation, a leaf, a piece of shipping foam nobody ever removed, ends up against the blade.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.
Reviews
The freezer in our shop building frosted over every summer and I'd chip it out and back it came. He tested the heater and the sensor, both fine, and told me straight that the room gets too hot out there in August. First person who talked me out of a part.

The wind week took our power out for two days and the Thermador column came back with an alarm showing and no ice. He was out next morning. The alarm was just a record of the outage, and the drain had set solid on the way back down.

I had the old 600 series written off and was pricing replacements. He said the sealed system was healthy and it came down to an evaporator fan and a gasket that had stopped pulling. The kitchen was built around that cabinet, so that mattered.

Questions
Frequently asked questions
Do you cover De Luz, Rainbow, Pala and the north end of Vista?
Yes. Fallbrook, Bonsall and Valley Center first, then Rainbow, De Luz, Pala Mesa, Pala, north Vista, south Temecula and Camp Pendleton. Distance is rarely the awkward part; access is. Gates, keypads, shared driveways and grove roads no mapping service knows turn an appointment into a phone call from the bottom of your hill. Give us the gate code and a landmark at the turn.
What does the visit itself involve, and how is it charged?
The technician diagnoses the appliance where it stands, grille and panels off, readings taken at the component rather than the display. There is a diagnostic charge for that visit, quoted when you book, and usually credited toward the repair if you go ahead. The repair is priced once the fault is known, as one figure covering part and work, agreed before anything is fitted.
