The short answer
On a Danby refrigerator, what the noise is and whether it matters comes down to a short list, and on this line the order is not the generic one. The diagnosis starts at a condenser fan blade catching debris, because the fan sits in the dirtiest part of the cabinet, and a leaf, a bag or a build-up of lint is enough to make it clatter. The first three checks below need no tools and no parts; the point at which this stops being an owner job is stated further down, as a condition rather than as a recommendation.
What you are seeing
- A rattle or buzz that starts and stops with the compressor.
- A repeated clicking every few minutes from the back of the cabinet.
- A whirr or a warble from inside the freezer that changes when the door is opened.
- A gurgle or a trickle after the cabinet shuts off, which is normal refrigerant movement.
- A knock or a bang when the cabinet starts, as though something shifted.
- A scraping or ticking that appears only after the cabinet has been running a while.
- Note: Near-miss symptoms that mean a different fault: If the noise is accompanied by a rise in temperature, treat it as a cooling fault first — the noise is a symptom, not the problem. If the noise stops when the door is opened, it is the evaporator fan, and that is an airflow question. A gurgle, a hiss and a soft pop as the cabinet cycles are normal and need no repair at all.
Causes, ranked for a Danby refrigerator
- A condenser fan blade catching debris — Why this rank: The fan sits in the dirtiest part of the cabinet, and a leaf, a bag or a build-up of lint is enough to make it clatter.
- A cabinet that is not level or is touching the wall or a cabinet side — Why this rank: Compressor vibration transmits into anything it touches, and this is by a wide margin the most common cause of a new noise.
- The wrong platform assumed at the start of the diagnosis — Why this rank: The Danby badge covers several unrelated platforms, so a large share of wrong turns here begin with a manual-defrost cabinet being treated as a frost-free one, or a portable machine as a plumbed-in one.
- A drip pan or a rear panel vibrating — Why this rank: The pan sits loose over the compressor by design, and a small shift turns it into a sounding board.
- An evaporator fan blade fouling ice or a failing fan bearing — Why this rank: It is the only motor inside the cold space, and the door-open test identifies it in seconds.
- A start relay or overload clicking repeatedly — Why this rank: Regular clicking on a several-minute rhythm is a compressor that is trying and failing to start, which is a fault and not a noise.
What to check, in order
- Note whether the noise runs with the compressor, with the door open, or on its own rhythm. — Order: First — Why: These three timings map to three different parts of the cabinet, and no further test is worth doing before you know which.
- Put a level on the cabinet and press a hand firmly on the top and on each side while it is running. — Order: Second — Why: If the noise changes under hand pressure it is a mounting or contact problem, which is the top-ranked cause and the cheapest fix.
- Open the freezer door with the light switch held in and listen for the fan changing note. — Order: Third — Why: It separates the inside fan from everything outside the cabinet in one move.
- Unplug the cabinet, pull it out and check the drip pan, the rear panel screws and the condenser fan blade. — Order: Fourth — Why: These are the three loose items at the back, and all three are visible and hand-checkable.
Steps a homeowner can take
- Unplug the appliance or switch off its breaker before you remove any panel or reach behind the cabinet. — Tools: none — Time: a moment
- Level the cabinet with its front feet and confirm nothing touches the wall, the counter or an adjacent cabinet. — Tools: spirit level, adjustable wrench — Time: several minutes
- Pull the cabinet out and reseat the drip pan, then tighten the rear access panel screws. — Tools: nut driver or screwdriver — Time: half an hour or so
- Clear the condenser fan area of dust, packaging and anything that has fallen behind the cabinet, and spin the blade by hand. — Tools: vacuum, flashlight — Time: half an hour or so
- Empty the freezer and check whether the fan blade is striking a frost build-up on the shroud. — Tools: flashlight, towels — Time: several minutes
- Time the clicking with a watch — a regular several-minute rhythm is the overload, not a loose part. — Tools: a watch — Time: half an hour or so
Before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never put a hand near a condenser fan blade while the cabinet is plugged in — the fan starts with the compressor and gives no warning. Do not push, bend or lever any tubing at the back of the cabinet.
When this stops being an owner job
Call when the noise is a regular click on a several-minute rhythm, when it comes from inside the sealed compressor housing, or when it is accompanied by a temperature rise. Levelling, a loose pan and a fouled fan are owner work; a bearing inside a sealed motor is not.

Generalized information
This page is generalized: it covers Danby across a whole refrigerator range rather than one family or one model, and where a more specific page exists it is linked here. It does not cover the Danby Designer, Danby Premiere and Danby One Plug sub-lines and their model-level pages, and it does not carry serial-range or model-group detail — check the rating plate before ordering any part. It is the larger frost-free half of the Danby refrigerator range; the compact and manual-defrost Danby cabinets are covered separately and linked above.
