AGA ranges
Cast iron with a memory. Diagnosed hot, not cold.
AGA spans two worlds: legacy heat-storage cookers with no electronics at all, and the modern eR7 line whose field-service manual documents one of the richest code sets in luxury cooking. Elise and Mercury ride the proven Rangemaster platform in between.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.

eR7 100 / 150 / 210
Touchscreen cast-iron ranges with individually switchable ovens and hotplates.
Farmhouse
Elise 36 / 48
Dual fuel or induction on the Rangemaster platform.
Contemporary
Mercury 36 / 48
Modern styling, dual fuel or induction.
Legacy
R7 and heat-storage cookers
Thermostatic gas and electric heat-storage AGAs - no codes, pure craft.
Start with the symptom
Common AGA range problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Cooling
AGA feels cooler than it used to
Thermal-mass behavior first: usage patterns, then thermostats and elements - diagnosed hot, the way the failure appears.
Zones
One eR7 zone dead
Relay, triac or thermocouple territory - the stored PCB code names the circuit.
Symptom
Elise induction cuts out
E2 overheat pattern: ventilation and boil-dry review before boards.
Symptom
Hotplate lid or lid seal wear
Cast-iron furniture parts are orderable through Middleby Residential.
Symptom
AIMS schedule confusion
Slumber and wake programming on legacy electrics is often settings, not faults - we check before charging for parts.
Symptom
Enamel chips
Cosmetic vitreous enamel repair guidance comes with honest expectations.
Series and model numbers
AGA range series we service
AGA generations differ radically - a legacy cooker diagnoses by temperature behavior, an eR7 by PCB codes. The badge decides the visit.
eR7
eR7 install codes
Model numbers
eR7 100-3, eR7 150-5, eR7 210
What to note
Codes are stored on the main PCB and read with AGA's TEK Vision service software.
Elise / Mercury
Platform models
Model numbers
Elise 36/48 DF or induction
What to note
Shares the Rangemaster platform with the CornuFé - parts availability is comparatively good.
Legacy

Total Control, Dual Control era
What to note
AIMS scheduling on later electric models; behavior questions are often usage, not faults.
Model label
Where to find your AGA model number
eR7: the data badge sits behind the removable magnetic plinth cover. Elise: in the drawer cavity - remove the storage drawer. Rangemaster-platform models generally carry the badge on the oven frame near the plinth. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
AGA range alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
Slow recovery on a heat-storage AGA
What it means
Cast iron cooks from stored heat - open lids, cold plain shelves and oversized pans drain it faster than it recovers.
Safe check
Give the cooker time with lids down; if recovery stays slow overnight, book the visit.
Message / alert
Blinking or dark eR7 touchscreen
What it means
FE, VE and CE codes cover panel and controller communication.
Safe check
Photograph the display; codes are stored on the main PCB and read during service.
AGA diagnostics
AGA range error codes, decoded.
eR7 codes come verbatim from AGA's official US field-service manual - one of the best-documented luxury platforms. Legacy R7 and heat-storage cookers have no codes at all: they are thermostatic and mechanical, and that is stated plainly rather than invented around.
Error code · FE / VE / CE
Panel and controller communication
What it commonly means
The touch panel is unresponsive (FE), firmware is incompatible (VE) or the main controller stopped answering (CE).
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Panel and controller diagnostics via AGA's TEK Vision interface; the failed board or firmware path is corrected.
Error code · 010-014
Full-power timeout
What it commonly means
A zone ran at full power longer than expected - very often usage-related on a thermal-mass cooker, not hardware.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Usage review first (doors, shelves, pan sizes); genuine faults move to element and thermocouple testing.
Error code · 020-024 / 060-100
Thermocouple faults
What it commonly means
Differential or open-circuit thermocouple readings on a zone.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Thermocouples are duplex four-wire parts that often fail only at temperature - they are tested hot, then replaced.
Error code · 110-116 / 150-156
Relay short or open
What it commonly means
A zone relay failed shorted or open on the main PCB.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Relay and PCB service with element resistance verified (18-20 ohms is the healthy band).
Error code · 120-124
Zone overheat
What it commonly means
A zone overheated - cross-connected thermocouples are a documented cause.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Wiring order is verified and corrected; sensors tested before any element is condemned.
Error code · 130-136
Triac fault
What it commonly means
A zone triac failed on the control board.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Element checked first, then the triac/board path repaired.
Error code · E2 / U400 / Er (Elise induction)
Induction platform codes
What it commonly means
Electronics overheated (E2), supply mis-connection (U400) or an internal fault (Er + number).
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Ventilation, connection and board diagnostics per the Rangemaster platform - identical to the CornuFé scheme.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
AGA products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.

Preventive service and owner care
AGA range maintenance
Alpha Pro provides preventive and general maintenance for AGA ranges. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Burners and grates: keep burner ports, caps, and igniters clean and dry; reseat caps correctly after cleaning.
Oven cavity: wipe spills once cool; follow the manual before using self-clean, which stresses components.
Control surfaces: clean knobs and panels with mild cleaner; never soak knobs or spray into switches.
Gas connections: leave gas fittings and conversions to qualified technicians only.
Professional maintenance
Inspection follows the appliance design
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Burner ignition and flame quality
Igniters, spark modules, and safety valves
Oven temperature accuracy and calibration
Bake and broil elements or burners
Convection fan operation
Door hinges, springs, and gasket
Control response and displayed faults
Gas smell, soot, or discoloration evidence
Diagnosis before parts
A straightforward three-step service process
1
Describe the symptom
Call or book with the model label, exact behavior, any displayed codes, photos, and access notes.
2
Evaluate the system
The technician examines the reported condition in context: ignition, flame quality, temperatures, elements, controls, door fit, and relevant components.
3
Review the recommendation
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.
Service areas and operating context
AGA ranges across San Diego
Alpha Pro serves AGA ranges in communities including La Jolla, Del Mar, Rancho Santa Fe, Carmel Valley, Poway, and the full San Diego County footprint below — ZIP by ZIP. Installation and room conditions vary from the coast to inland homes.
Coastal homes
Moisture, ventilation, and accessible surfaces
Recurring condensation, marine exposure, ventilation limits, and visible corrosion can be useful details during repair or maintenance.
Inland homes
Ambient heat and equipment environment
Share room conditions, recent heat events, ventilation restrictions, and when the symptom appears.
During maintenance, accessible metal surfaces can be inspected for corrosion, moisture exposure, or conditions that may warrant attention. Location alone does not establish the cause of a failure.

Helpful answers
AGA range service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day AGA range repair in San Diego?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a AGA range?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
Do AGA cookers have error codes?
The modern eR7 line does - a rich, officially documented PCB code set (FE/VE/CE plus numeric 002-159) read via AGA's service interface. Legacy heat-storage cookers have none: they are thermostatic and mechanical.
Why is my cast-iron AGA slow to recover heat?
It cooks from stored heat. Open lids, a cold plain shelf in the simmer oven or oversized pans drain the mass faster than the elements recover it. If overnight recovery stays poor, a thermostat or element visit is warranted.
Where is the model number on an AGA?
eR7: behind the removable magnetic plinth cover. Elise: in the drawer cavity after removing the storage drawer.
Why do AGA thermocouples get tested hot?
They are duplex four-wire parts known to fail only at temperature - a room-temperature test can pass a faulty one. Testing hot is the honest method.
Are AGA parts available in the US?
Yes - AGA is a Middleby company with US parts through Middleby Residential, and the Elise/Mercury platform shares the widely stocked Rangemaster parts system.
