Mercury Range Cooker Repairs
A Brassett Ltd provides independent Mercury range cooker repair support from Bromley across London and a broad South East service area. We handle current Mercury 1000, 1082 and 1200 models, plus older RC1090, RC1100 and Thermastone-era enquiries where parts availability needs careful checking.
Family-run appliance repair specialists since 1984
A Brassett Ltd provides domestic appliance repair support for homeowners, landlords, letting agents and property managers. Mercury range cookers are substantial appliances, so the exact model, serial number, fuel type and fault description are important before a visit is arranged.
We are an independent repair company and do not claim manufacturer authorisation. We do not repair gas leaks or gas-supply faults.
What to send before booking
Mercury Range Cooker History
Mercury has moved through several ownership stages while remaining a distinctive premium range-cooker name. Earlier domestic Mercury cookers were developed under Lincat. In 2009 AGA Rangemaster acquired the Mercury domestic range-cooker business and principal assets. AGA Rangemaster later became part of Middleby's residential kitchen portfolio.

Where Mercury Sits Today
Mercury is part of the AGA Rangemaster family. AGA Rangemaster's current brand information places Mercury alongside AGA, Rangemaster and Falcon, with Rayburn also within the wider group. These are related brands rather than interchangeable products, and parts should always be identified from the exact model and serial number.
Current premium range-cooker line with 1000, 1082 and 1200 sizes in dual-fuel and induction formats.
Part of the same wider AGA Rangemaster residential-kitchen family. The AGA Masterchef Deluxe is a current conventional range-cooker line in 90 cm and 110 cm widths.
AGA Rangemaster's principal range-cooker brand and the current route used for many Mercury spares and support references.
A related AGA Rangemaster range-cooker brand. Product construction and components can overlap by platform, but compatibility must never be assumed.

Current Mercury 1000, 1082 & 1200 — Replacing an Older Cooker
The present Mercury family remains the 1000, 1082 and 1200, with dual-fuel and induction versions. They can be considered when an older Mercury is beyond economical repair, but they are not automatic like-for-like replacements for RC1090, RC1100 or Thermastone-era appliances.
Current 100 cm-class Mercury; official specification lists a 990 mm width.
- Dual-fuel or induction
- Two electric ovens
- Separate grill
- Check old opening width and service positions
Distinctive 1082 mm-wide current Mercury format.
- Dual-fuel or induction

- Two electric ovens
- Separate grill
- Suitable only where the kitchen opening and services match
Before replacing an old Mercury
Measure the actual cooker width, depth and height, check worktop and plinth clearances, cooker-hood spacing, electrical supply, gas connection if applicable, and the position of services behind the appliance. A newer Mercury, AGA Masterchef Deluxe or Rangemaster may be worth comparing, but none should be treated as a direct replacement without checking the installation.
Current Mercury product family and related AGA Rangemaster brand information are based on current AGA/AGA Rangemaster product pages. Exact specifications can change by production revision.
Many Older Mercury Parts Are Now Obsolete
This is particularly important with earlier Lincat-era Mercury range cookers. Genuine parts for some older models are no longer produced or routinely supplied, and parts catalogues show numerous older Mercury components as obsolete or no longer available.
RC1090, RC1100 and Thermastone-era cookers can be difficult. Certain switches, grill components, burner parts, hinges, cosmetic controls and model-specific components may no longer be available through normal channels. Rangemaster's current service information also lists Mercury Thermastone and RC1090 products as exclusions from its fixed-price service.
This does not automatically mean the cooker is beyond repair. Depending on the failed component, remaining genuine stock, compatible alternatives, reclaimed stock or specialist replacements may sometimes exist.
Please send the full model, serial number, a clear rating-plate photo and fault details before booking an older Mercury. A Brassett Ltd cannot guarantee an older Mercury repair until the failed component has been identified and availability checked.

Mercury Range Cooker Fault Checker
Choose the closest symptom. This is guidance for describing the fault, not a diagnosis. For older Mercury cookers, model and serial information is critical because components can differ and some are obsolete.
Please have the model, serial number, fuel type and full postcode ready.
Common Mercury Range Cooker Faults
Electrical oven, grill, induction, door, control and timer faults are common repair enquiries. If a cooker repeatedly trips the electrics, overheats uncontrollably, sparks internally or gives a burning smell, stop using it until checked.
Oven not heating
If the display or fan works but there is no heat, possible causes include an element, selector, thermostat/sensor, relay, wiring or control component. Model and serial details are essential before parts are ordered.
Fan oven runs but does not heat
A fan oven that circulates air but produces no heat may have an element or electrical-control fault. Older Mercury element availability can vary by model.
One oven cavity not working
Mercury range cookers use separate oven cavities and controls. Tell us whether the left or right oven is affected and which functions still work.
Grill not heating
A failed grill element, selector, wiring or control can cause no or partial heat. On older Mercury models, some original grill components may now be obsolete.
Oven overheating
Stop using the affected cavity if temperatures appear uncontrolled. A thermostat, sensor, selector or electronic control fault may need investigation.
Oven not reaching temperature
Slow warm-up or low temperature can involve heating elements, door sealing, sensing or control faults. Note the cooking mode and approximate temperature behaviour.
Oven fan noisy
Rattling, scraping or grinding can indicate a worn fan motor, blade contact or mounting issue. Stop use if the noise becomes severe.
Cooling fan keeps running
Extended cooling-fan operation can be normal after cooking, but continuous running may point to a temperature-sensing or control issue.
Door will not close properly
Worn hinges, hinge receivers, catches or distorted seals can prevent correct closure. Older Mercury hinge and door parts need checking by exact model.
Door seal damaged
A damaged seal can cause heat loss and uneven cooking. Send clear photos because seal profiles and lengths vary between Mercury generations.
Clock or timer fault
If the oven will not operate after a power cut or the timer is blank, flashing or unresponsive, note the exact display behaviour and model.
Control knob or selector fault
Loose, cracked or non-responsive controls can involve the knob, spindle, switch or selector behind it. Some older cosmetic/control parts are difficult to source.
Cooker trips electrics
Stop repeated resetting and isolate the appliance safely. Elements, wiring, motors, induction electronics or other components may have an insulation fault.
Induction zone not working
Current Mercury induction models use a five-zone induction hob. Note which zone fails, any error code and whether other zones operate.
Induction error or power fault
Induction faults can involve power modules, cooling, sensors or supply conditions. Send the exact code plus the full model and serial number.
Ignition clicking or electrical ignition fault
On dual-fuel models, electrical ignition faults can be discussed, but A Brassett Ltd does not repair gas leaks or gas-supply faults.
Old Mercury part unavailable
For RC1090, RC1100, Thermastone-era and other older Mercury cookers, some genuine parts are obsolete. We will need the exact model, serial number and part/fault details before confirming whether a repair is viable.
Other Mercury fault
Send the complete model and serial number, approximate age, fuel type, which oven/hob section is affected, the exact symptoms, full postcode and clear photos.

Please send the full model and serial number, approximate age, fuel type and a clear description of the fault. For an older Mercury, add a rating-plate photo and, where safe, a photo of the failed component or control. This helps us check whether the likely parts are still obtainable before an engineer travels.

Mercury Range Cooker Repair FAQs
Useful answers about Mercury models, older parts, current replacement options, ownership history and our Bromley-centred service area.
Do you repair Mercury range cookers?
Yes. A Brassett Ltd accepts selected Mercury range cooker repair enquiries for current and older models, subject to the exact fault, appliance condition, access, engineer route and parts availability.
How far does your Mercury cooker repair service cover from Bromley?
Our route network covers Bromley, London and a broad South East area extending roughly 100 miles from Bromley. Individual postcodes are subject to engineer route and booking availability.
Which Mercury models do you cover?
Enquiries are welcome for current Mercury 1000, 1082 and 1200 models and older Mercury ranges including RC1090, RC1100 and Thermastone-era appliances, although older parts availability must be checked.
What are the current replacements for older Mercury range cookers?
The current Mercury family includes the 1000, 1082 and 1200 in dual-fuel and induction versions. These are not automatic like-for-like replacements for older Mercury models, so width, depth, services, ventilation and electrical or gas requirements must be checked.
Who took over the Mercury cooker brand?
Mercury began under Lincat. AGA Rangemaster acquired the Mercury domestic range-cooker business in 2009. Middleby acquired AGA Rangemaster Group in 2015. In February 2026 Middleby completed the sale of a 51% stake in its Residential Kitchen business to 26North, retaining a 49% non-controlling interest.
Which brands are now related to Mercury?
Mercury sits within the AGA Rangemaster family alongside brands including AGA, Rangemaster and Falcon, with Rayburn also within the wider group. These brands are related but their parts and appliances are not automatically interchangeable.
Are many old Mercury cooker parts obsolete?
Yes. A significant number of genuine parts for older Mercury cookers are obsolete or no longer routinely supplied. RC1090 and Thermastone-era machines need especially careful parts checks.
Can an obsolete Mercury part sometimes be replaced?
Sometimes. Remaining genuine stock, compatible alternatives, reclaimed stock or specialist replacements may exist, but compatibility cannot be promised until the failed component and exact model have been identified.
Do you repair gas leaks on Mercury dual-fuel cookers?
No. A Brassett Ltd does not repair gas leaks or gas-supply faults. Electrical oven, control and ignition-related enquiries can be discussed where they fall within our repair scope.
