Why Your Refrigerator Runs Constantly

A refrigerator that runs constantly, rarely shuts off, and starts freezing food in the fresh-food section usually has dirty coils, a leaking gasket, a failing fan, or a thermostat or temperature sensor that can no longer tell the system to stop. Check temperatures in both sections first.

If your fridge has not cycled off in hours and lettuce is freezing, call Cibolo Refrigerator Pros at (830) 555-0147. Tell our friendly staff the temperatures you are seeing, your brand and model number, and whether the sides of the cabinet feel hot. That helps our knowledgeable technician plan a quick diagnosis on the first visit.

How long should a refrigerator actually run?

Homeowners picture a fridge running in short, quiet bursts. Modern units run more than older ones did — longer, lower-power cycles are normal, and in a Cibolo summer a healthy fridge may run 70% to 90% of the day. Running a lot in August is not, by itself, a failure.

Running constantly means something more specific: the compressor almost never stops, day and night, even when the kitchen is cool and the doors have stayed shut. Pair that with food freezing in the fridge side, ice building up, hot cabinet sides, or a rising electric bill, and the system is telling us it cannot reach or cannot sense its target temperature.

Start with two thermometers, one in each section. The freezer should hold 0°F and the fridge 37°F to 38°F. If the fridge side reads 30°F to 33°F and milk is slushy, the system is over-cooling. If both sections read warm while it runs nonstop, it is under-cooling despite the effort. Those are two different repairs.

If the freezer side will not freeze at all, read freezer not freezing. If noise came first, see refrigerator noises — a straining system often gets loud before it gets warm.

Why is food freezing in the refrigerator section?

This is the symptom that confuses people most, because the fridge is clearly working — too well. The usual causes, in the order we check them:

• Thermostat or temperature sensor failure. The control thinks the fridge is warmer than it is, so it never stops cooling. This is a classic thermostat failure sign: wildly wrong section temperatures, food freezing at the coldest settings, or no response when you change the dial.
• Stuck or broken air damper. The damper controls how much freezer air enters the fridge side. Stuck open, it floods the fresh-food section with 0°F air.
• Settings and placement. A fridge set to its coldest level, or food pushed against the back wall or directly under the air vent, freezes even in a healthy unit. Move produce away from the vent and confirm settings before booking.
• Control board fault. Less common, but a board that misreads the sensor can drive nonstop cooling. Board work nationally runs $200 to $500, so we prove the sensor and damper first.

Thermostat failure signs worth telling us about: temperatures that swing several degrees for no reason, a control that feels loose or clicks without changing anything, frost patterns that changed at the same time, and a fridge that only behaves at one specific dial position. Those details separate a $100 to $250 thermostat or sensor repair from a parts-guessing exercise.

Could dirty coils and Cibolo heat be the whole problem?

Often, yes — and this is the version where the fridge is not over-cooling but struggling. The condenser coil releases the heat removed from your food. Coat that coil in dust, pet hair, and oak pollen, then ask it to work in a hot room, and the compressor has to run far longer to do the same job. Eventually it runs all the time and still falls behind on the hottest afternoons.

Cibolo stacks the deck. August highs average around 96°F with heat index readings routinely above 105°F. Refrigerators are tested around a 90°F ambient, so a kitchen unit is already past its comfort zone in a house where the AC is set high during the day, and a garage unit in Legendary Trails or Green Valley Ranch can face 100°F to 130°F ambient — well beyond a standard unit's rating. Add construction dust from the building boom along FM 1103, where new homes in Venado Crossing and Buffalo Crossing sit next to active lots, and coils clog faster here than the manual assumes.

The Cibolo-specific paragraph test is simple: a fridge in a 2008-built home — the median build year here — that has never had its coils cleaned, running nonstop through its fifteenth August while 39,019 neighbours run their AC and garage freezers on GVEC power, is not a mystery failure. It is maintenance meeting climate. Cleaning the coils is the first step, and if run times do not drop within a day, we keep diagnosing.

What about a door gasket leak or a failing fan?

A leaking door gasket lets warm, humid air in around the clock. The fridge cools it, more leaks in, frost builds, and the compressor never gets a break. Run the dollar-bill test around the door: if the bill pulls out with no drag, that stretch of gasket is not sealing. Torn or hardened gaskets are common on the 10- to 16-year-old fridges now filling Cibolo Valley Ranch and Bentwood Ranch kitchens.

Fans matter just as much. A weak condenser fan lets the coil overheat. A failing evaporator fan moves cold air poorly, so the coil gets colder and colder while the sections stay uneven — freezing near the vent, warm in the door bins. A courteous technician checks both fans, the gasket, and the coils before quoting control parts. Diagnose the whole system, not just the first suspicious part is not a slogan; on this symptom it is the difference between one visit and three.

Humidity feeds the same spiral. Every leak and every long door opening during unloading adds moisture that becomes frost, frost insulates the coil, and run times climb again. If frost is visible on the back wall, read refrigerator frost and ice buildup alongside this page.

How much does it cost to fix a refrigerator that will not stop running?

Nationally, Angi puts the average refrigerator repair at $275, with most jobs between $150 and $400. The repairs behind this symptom mostly sit in the lower bands: thermostat, defrost, and fan repairs typically run $100 to $250, a door gasket $75 to $200, and control board work $200 to $500. A compressor is $300 to $800, but nonstop running alone is rarely a compressor diagnosis — we only go there if sealed-system tests prove it.

Our promise is cost transparency. The service call diagnostic fee is one flat fee, confirmed before we dispatch. You get an explanation of the problem, a written quote separating parts and the labor charge, and repairs covered by a written parts-and-labor warranty. If the honest answer is a coil cleaning and a gasket, that is what our honest staff will quote — not a board you do not need.

There is also a running cost to doing nothing: more electricity, a compressor worn years early, and a risk of total cooling loss in the next heat wave, when perishables above 40°F for more than 2 hours should be discarded. Full pricing is on our refrigerator repair cost page and the refrigerator repair hub.

When should you call instead of watching it another week?

Call promptly if food freezes daily, cabinet sides are hot, frost builds fast, or temperatures are out of range. Also call if run times spiked after a surge or outage — controls and sensors are surge-sensitive, and Cibolo storm season gives GVEC customers a few of those every year. Same-day availability depends on schedule, location, and repair type, and calling early improves the chance.

Frequently Asked Questions

Is it normal for a refrigerator to run all the time in Texas summer?

Running most of the day is normal in a Cibolo August, when highs average around 96°F. Running with almost no off cycles at night, freezing food in the fridge side, or falling behind on temperature is not normal. Those patterns point to coils, gasket, fan, thermostat, or sensor trouble.

Why is my refrigerator freezing food on the fridge side?

The fridge side gets too much cold air or the control never tells it to stop. Common causes are a failed thermostat or temperature sensor, a damper stuck open, the coldest setting being selected, or food blocking the vent at the back wall. Check settings and food placement first, then book a diagnosis if it continues.

What are the signs of a bad refrigerator thermostat?

Inconsistent temperatures, food freezing even at warmer settings, a control dial that changes nothing, and a compressor that runs constantly or short-cycles are the classic signs. A technician confirms it by comparing actual section temperatures against what the control is sensing.

Can dirty condenser coils make a fridge run constantly?

Yes. A coil blanketed in dust and pet hair cannot release heat, so the compressor runs longer and hotter to hold temperature. In Cibolo, heat, humidity, construction dust, and garage placement make this worse. Cleaning the coils is the first check before quoting any parts.

How much does it cost to fix a fridge that runs nonstop?

It depends on the cause. Nationally, thermostat and fan repairs typically run $100 to $250, a gasket $75 to $200, and a control board $200 to $500. Most refrigerator repairs are $150 to $400, averaging $275. Our diagnostic fee is one flat fee, confirmed before we dispatch, with a full quote before work begins.

Will a refrigerator that runs constantly burn out?

It can. Constant running wears the compressor and fans, raises your electric bill, and often ends in a full cooling failure during the hottest week of the year. Catching a sensor, fan, or coil problem early is far cheaper than a compressor replacement at $300 to $800.

Your fridge should get to rest, and so should your electric bill.
