The short answer
Amana BD owners usually report this as "it runs all the time and nothing is cold", and that phrasing is the diagnosis. Six model numbers carry this family badge, and the matrix on this page is the list. A unit chasing a setpoint it cannot reach has lost airflow, not refrigerant, and the order below reflects that.
Symptoms on these models
- A sheet of frost on the freezer rear wall — Ice forms a slab across the back panel instead of a thin even coat — the tell that airflow has already stopped.
- The fresh-food side warms before the freezer does — On a single-evaporator cabinet the fresh-food side is fed by air from the freezer, so it loses temperature first.
- The compressor never shuts off — It runs continuously without reaching setpoint — the same fault seen from the other side.
- NEAR MISS — the unit is silent and nothing is cold — Silence changes the diagnosis completely: start there with power and the start device, not with airflow.
What it usually is, in order
- Door seal, door alignment or a door left ajar — First on the BD line because the cheapest check comes first on principle: a gasket that has taken a set, or a door held fractionally open by a drawer, admits warm room air continuously and costs nothing to rule out.
- Stalled defrost cycle icing the evaporator — Second because the two are linked. Humid air admitted past a tired gasket freezes onto the evaporator faster than the defrost cycle can clear it, so the door fault produces the ice fault.
- Evaporator or condenser fan not running — Third because with the door and the defrost circuit accounted for, a fan that has stopped is the remaining way for cold air to fail to arrive — and listening at both takes a minute.
- Compressor start device or sealed-system fault — Last. It is the least likely and the most expensive, so it is the one that should be confirmed rather than guessed.
What to check first, second, third
- Close the door on a strip of paper at several points — It costs nothing and it goes first: a gasket that lets the paper slide out freely is admitting warm air continuously.
- Check the door is being closed at all — A shelf or a drawer fouling the door, or a cabinet leaning back, keeps a door off its seal in a way the owner stops noticing.
- Look behind the freezer rear panel for ice — The humidity a bad seal admits ends up on the evaporator, so this check confirms how long the leak has been running.
- Listen for both fans, then feel the condenser — Listen for both fans and feel the condenser last, because these are the checks that need the cabinet moved or a panel off.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Do not defeat or tape the door switch to keep the fan running while you work, and do not thaw an iced evaporator with a heat gun or a knife — the tubing behind that ice punctures easily, and a punctured sealed system turns a small repair into a replacement.

When to call a technician
The condition on these models is simple: if the next step needs gauges, a meter or the evaporator exposed, it is a service call. Everything before that point is a look and a listen. Do not run a cabinet that trips its breaker in the hope of keeping food cold — it will not, and the fault is electrical.
