The short answer
A running MS refrigerator that stays warm is telling you that cold is being made and not delivered. The table on this page carries a single model number, so everything here describes one build. That distinction is what separates the owner-side checks here from the brand-generic advice, which starts at the compressor.
What an owner actually sees
- Ice cream is soft while the freezer looks frosted — The compartment is above its holding temperature even though it looks cold, which is what a marginal capacity loss looks like from the inside.
- The unit never cycles off — A compressor that runs without a break is a compressor that never reaches its cut-out point. Continuous running is the same fault seen from the control side.
- A strong smell inside despite normal cleaning — Usually a consequence rather than a cause: the cabinet has been above its holding temperature for long enough to spoil something.
- NEAR MISS — the cabinet is silent and nothing is cold — Silence changes the question entirely: that is a no-power, start-device or control fault, and it belongs on a different page.
Ranked causes for these models
- The compressor start device — First on the MS family. A start device that is failing intermittently lets the compressor start, run briefly and drop out on its overload, so the owner hears a machine that is clearly working and finds a cabinet that never gets there.
- The temperature control — Second. On these models the control is a simple device with a sensing element, and when that element loses contact with its mount the control reads the wrong temperature and satisfies early.
- Condenser airflow and dust — Third. A coil packed with dust or a cabinet pushed back against a wall both produce the same outcome, and on this family the coil is easy to reach from behind.
- The seal and how the cabinet is packed — Fourth. Overloading blocks the internal vents on cabinets of this size, and a seal that leaks adds moisture that ends up as frost.
- Refrigerant loss or a restricted sealed system — Last, by elimination only. A slow loss shows as a cabinet that cools a little and a compressor that never stops, but so do three cheaper causes above it — so it should be the conclusion of a diagnosis, never its opening guess.
What to check first, and why that order
- Put a thermometer in each compartment and wait — Start with a measurement rather than an impression, because what the cabinet actually holds decides everything below.
- Compare the two compartments against each other — One warm and one cold is a distribution fault; both warm is a capacity fault. That single comparison splits the list.
- Pull the cabinet out and look at the back — Clearance, dust and a fan that should be turning are all visible here in a couple of minutes.
- Change one thing, then wait a full day before judging — These cabinets take hours to settle, and changing two things at once destroys the information the wait would have given you.
Safety first
Safety
Power off at the breaker or the plug before any cover comes off, and treat the compressor area as live until it is. Leave the door switch wired as it is: it cuts power to the internal fan for a reason, and defeating it puts a moving blade in reach of a hand. Anything on the sealed system is licensed work; do not open refrigerant tubing. While the cabinet is warm, treat the food by the clock rather than by the look of it: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below. Above those, move anything perishable to a cooler with ice and keep the door shut.

When to call a technician
Call once the owner-side checks are clean: seal, loading, clearance and a visible look at the evaporator area. Call immediately if you see oil at the compressor or smell burning, because oil outside the tubing means the sealed system is open and every further hour of running makes the repair larger. On the MS family the line between the two jobs is the panel: what you can reach with the cabinet emptied is owner work, what needs the machine dismantled is not.
