How to prevent your lift motor room from overheating in hot weather

How Often Should a Lift Be Serviced? The Importance of Lift Maintenance and the Risk of Overheating In Motor Rooms.

When it comes to ensuring the safety and reliability of passenger lifts, understanding the importance of regular service and knowing how often that maintenance should occur is imperative to the optimal health of your equipment’s life cycle.

Not only is it a legal obligation, but it also helps prevent issues like overheating, which can lead to severe lift malfunctions.

As the warmer months roll in, we’re reminded of one easily overlooked but critical factor in lift performance: the temperature inside the lift motor room. Without proper ventilation or regular maintenance, these spaces can quickly overheat, placing strain on the entire lift system. So if you’ve ever wondered why that six-month lift service is so crucial, here’s a closer look.

Why Lift Maintenance Frequency Matters. It is generally advised that lifts be serviced at least once every six months, though the ideal frequency will depend on a few variables:

• • Frequency of use
  • In line with O&M documentation requirements
  • Age and condition of the lift
  • Environmental factors (temperature, humidity, etc.)
  • Type of building (public, residential, commercial)

High-traffic lifts or those exposed to more demanding environments may require more frequent checks. Regular lift maintenance not only ensures compliance with legal standards but also reduces downtime, prevents faults, and maintains passenger safety.

Legal Requirements You Need to Know Passenger lifts fall under LOLER (Lifting Operations and Lifting Equipment Regulations). These require that lifts are thoroughly examined at regular intervals by a competent person. While LOLER inspections are not the same as servicing, regular maintenance is necessary to support these inspections and maintain full compliance.

Lift owners and duty holders are responsible for keeping accurate lift maintenance records and acting on any issues found during lift routine servicing. Failure to do so could lead to significant fines, legal consequences, or worse, serious safety incidents.

What Happens When You Skip Maintenance? Overheating is one of many consequences of inadequate lift maintenance. The ideal temperature for a motor room should be between 7 and 32 degrees Celsius (45–90°F), with humidity below 85%. Anything above this threshold puts your lift’s motor and control equipment at risk.

A few key causes of overheating:

• • High ambient temperatures during summer
  • Poor ventilation or blocked airflow
  • Malfunctioning fans or filters
  • An overloaded lift or one operating beyond its duty cycle
  • Voltage irregularities impacting electrical components

The effects? Equipment damage, trapped passengers, or even fire risks.

The Value of Regular Inspections and Maintenance. Routine inspections allow lift engineers to check:

• • Ropes, wiring, brakes, and mechanical parts
  • Door function, levelling, and emergency alarms
  • Ventilation and cooling systems in the motor room
  • Communication programs and environmental hazards (e.g., bird droppings)
  • Lubrication and cleaning of critical areas (shaft, car top, etc.)

These checks are essential not just for smooth operation, but also to detect early signs of wear and environmental stress that could lead to overheating.

When Should You Be Concerned? Be on the lookout for warning signs:

• • Unusual noises or vibrations
  • Doors failing to open or close properly
  • Inconsistent floor levelling
  • Faulty buttons or sluggish performance

Addressing these issues early can prevent escalations and reduce repair costs down the line.

What You Can Do Here are a few best practices:

• • Stick to your maintenance schedule
  • Educate tenants and staff on safe lift use (don’t hold doors open or overload)
  • Ensure your lift’s motor room is climate-controlled or well-ventilated
  • Keep detailed records of all lift servicing and inspections

The Solution: Proactive Lift Maintenance

Preventing overheating starts with routine, proactive lift maintenance. At VM Elevators, our engineers are trained to spot early warning signs and implement effective cooling strategies before failures occur.

Practical Measures Include:

• • Installing Climate Control Systems
    A dedicated cooling unit maintains stable conditions year-round.
  • Improving Ventilation
    Ensuring vents and filters are clean and functional supports airflow and prevents heat accumulation.
  • Fixing Underlying Mechanical Issues
    Whether it’s a fan motor, control unit or a worn bearing generating extra heat—our team diagnoses and resolves issues at the root.
  • Using Portable AC Units During Hot Spells
    For buildings without built-in climate control, a temporary AC solution can stabilise temperatures during peak heatwaves.
  • Routine Lift Servicing
    Regular lift servicing ensures all components, including cooling fans, wiring, and ventilation systems, are in top condition.

Partner with Professionals. Always use a qualified, experienced lift maintenance provider—like VM Elevators. Our engineers are trained not only to service lifts but to assess environmental factors that could cause system stress. And while we don’t carry out LOLER inspections ourselves, we will always work closely with third-party inspectors to make sure you’re always one step ahead of compliance.

Lift maintenance isn’t just about ticking boxes—it’s about protecting your passengers, extending the lifespan of your equipment, and keeping everything running safely and smoothly.
