Identify a faulty thermostat sensor before replacing the control in Kenilworth
We assess the sensor reading, thermostat position and demand response to distinguish a sensor fault from environmental or heating-system causes.
Booking fee plus hourly labour — the price is confirmed before any work starts.

If the thermostat reports an implausible room temperature or reacts unpredictably, a sensor may be involved, but replacement should not be assumed. We compare its readings and surroundings with system behaviour before advising on repair options.
What the symptoms can tell us
A temperature sensor can drift, fail intermittently or stop reporting, but location can produce similar symptoms. A control beside direct sunlight, an external draught, a radiator or heat-generating appliance may sense a local condition rather than the room generally. Remote sensors can be disconnected or incorrectly assigned, and a displayed number may be delayed. A thermostat that reads plausibly but does not switch the heating as expected may instead have a control or receiver issue. Note the displayed reading, any error code, recent relocation and whether the room feels different at various points. This helps separate sensor accuracy from heating output and settings.
Checks during the visit
The engineer identifies the thermostat and any linked sensors, then reviews the displayed temperature, status messages and normal response to user controls. Location, airflow and proximity to heat sources are considered; a comparison reading is interpreted by position and settling time. Where the product supports sensor checks or a documented diagnostic mode, it can be used in context. The engineer also checks whether the control issues a heat demand and whether the system reacts. A visit is not a laboratory certification of temperature accuracy or a full room survey. If a sensor is integrated into a control, the manufacturer's parts and replacement route may determine what is practical.
Repair choices and limits
If the sensor is remote and its connection or assignment is the issue, a supported correction may be possible. An integral sensor fault may require replacing the thermostat if it cannot be repaired and a suitable compatible model is available. Relocating the control can involve electrical work and should be based on a representative position, not solely one comparison measurement. If the sensor reading is reasonable, the fault may lie in the heating response or room heat distribution. The engineer explains the evidence and any limits; additional sensors or parts are identified and quoted before work starts.
Electrical and heating safety
A thermostat is a control device, not permission to work inside a boiler. Maintenance Men handles thermostat controls and suitable electrical or water-side heating faults within scope, but does not carry out gas work or open a gas boiler to adjust gas components. If symptoms suggest a combustion, flue or other gas-side safety concern, stop using the appliance if advised, leave it unopened, and arrange a Gas Safe registered engineer; an urgent gas smell is not a routine booking. Do not remove covers, probe live terminals or bypass a control. The engineer will explain any limit before proceeding.
Booking, price and next steps
The booking is for the stated diagnostic or defined thermostat visit, not an automatic promise that every fault can be fixed in one appointment. Booking fee is paid when booking; the hourly labour rate depends on how soon you need the visit. The full cost for the agreed work is quoted and you approve it before work starts. Any required replacement control, wiring materials or other parts can be identified and quoted separately; parts are not assumed to be included. Availability, compatibility and access may affect the next step. Book online and include the thermostat make and model, heating system type if known, symptoms, and anything already checked.
After the visit
Avoid heating, cooling or covering the thermostat to force a test reading. Take a comparison in a stable part of the room and record both values with the time and location. Keep sensor vents clear and do not clean inside the unit with liquids. If the reading is erratic, note whether the display changes abruptly or slowly. After any adjustment or replacement, allow the system and room to respond under normal use before judging the result, as room temperature changes more slowly than a display.
How the price works
We charge a booking fee to hold your slot, then an hourly rate for the work itself. The fee changes with how soon you need us; the hourly rate changes with the slot you choose. You approve the price before we start, so there is no surprise on the invoice.

We diagnose on site
The engineer confirms the cause and tells you what the job involves and how long it should take.
You approve, we work
Nothing goes ahead until you agree the price. Labour is then charged per hour at your slot rate.

What our customers say about our heating & radiators service
5 out of 5 from 10 reviews
Fast, tidy and friendly
Booked the £220 booking-fee slot on Tuesday and got a message confirming the time the same morning. The cause was explained, the price agreed before any work started, and the job was done in about 46 minutes. Clean and tidy when they left.
Job: No Heating from Boiler
Turned up when they said
What I appreciated was being told what was actually wrong before anyone started. Sorted in under 46 minutes and the invoice matched the quote to the penny.
Job: Expansion Vessel Fault
Exactly what was quoted
I had put off sorting this for months because I expected a runaround. Quoted the booking fee plus hourly rate upfront, stuck to it, and actually found the underlying cause rather than just clearing the symptom. Worked neatly and hoovered up afterwards.

Questions people ask about faulty temperature sensor
Straight answers to the things customers ask most often before booking.
Can I test the sensor with another thermometer?
You can compare readings in the same area after allowing both devices to settle, but the comparison is not formal calibration. Keep them away from sun, drafts and radiators and record where they were placed.
What will be checked?
The engineer reviews the model, sensor arrangement, location, displayed values and thermostat demand, then observes the heating response. Any linked remote sensor or status message is considered where applicable.
Can I open the thermostat to check its sensor?
No. A wired thermostat can expose electrical terminals, and an internal sensor may be delicate. Leave the casing closed and do not spray or probe inside.
Does a faulty sensor mean the whole thermostat must be replaced?
Not always. The model may support a separate sensor or repair, but an integrated failed sensor can make compatible replacement the practical option. The diagnosis and availability are checked first.
How are costs agreed?
The booking fee is paid when booking, and the hourly labour rate depends on how soon the visit is required. The full price is quoted for approval before work begins; sensors or other materials are quoted separately.
