Bathroom ceiling vent fans carry no warnings about continuous use. A fan in good condition, used in a good environment, will not heat excessively. However, a defective, older, or worn fan, or a fan that is binding or prevented from turning, or operated where airflow is blocked, can overheat, possibly dangerously. If a fan is making any kind of grinding or squealing noise, it should not be operated. A fan that does not turn freely should not be turned on. Such defective fans should be replaced, and it is good practice to replace any older ceiling fan (over six years) as a matter of course. They operate in harsh conditions, often ventilating moist or dirty, smoky air. A good quality, new fan will likely be quieter and more efficient, and it won't have the wear problems that can cause overheating. Potentially it is a fire hazard. Many vent fans use an open frame motor that depends upon air flow past it for cooling, and some vent fans are enclosed in plastic housings.
Over time, dust and lint can collect on this open frame motor, insulating it from the air flow and causing it to heat up. Eventually, if it gets hot enough, it can fail electrically and blow a spark. This spark can ignite the dust and lint, and if the housing is plastic the housing can ignite as well. This becomes a serious problem.
