Don’t see your issue? Just call — we’ve likely diagnosed it before.
When an AGA appliance stops working properly, it can quickly disrupt your cooking routine. We diagnose the actual cause of the problem instead of guessing, so you know exactly what needs to be repaired.
With experienced technicians and the right diagnostic tools, we handle everything from heating and temperature problems to electrical faults, control issues and AGA eR7 or R7 fault codes.
AGA range cookers combine multiple cooking functions in one appliance. We diagnose heating problems, temperature issues, thermostat faults, electrical failures, hotplate problems and control issues on AGA range cookers.
Common range cooker problems:
AGA refrigeration appliances are designed to keep food at a stable temperature, and faults can quickly affect food storage. We diagnose cooling problems, temperature fluctuations, unusual noises, leaks and electrical or control issues on compatible AGA refrigeration appliances.
Common refrigerator problems:
Most sites will tell you AGA publishes no fault codes. That is true of the owner manuals, and it is where our earlier version of this page stopped. It is not true of AGA’s field service documentation: the AGA eR7 Field Service Manual for the USA and Canada carries a full code table. These are the codes, with AGA’s own descriptions and the practical checks they point to.
| Code | AGA’s description / what it means on site |
|---|---|
| 002, 003, 006 | Communication watchdog fault Check the COMS cable and its connections first. The board only after the fault recurs. |
| 007 | Thermocouple reference fault The panel cannot process thermocouple readings correctly. |
| 010 to 014 | Full power time out Check thermocouple position and sometimes how the cooker is being used. |
| 020 to 024 | Thermocouple differential Exchange the thermocouple; this is the drift fault. |
| 060 to 100 | Thermocouple open circuit Test across the green and white conductors before replacement. |
| 110 to 116, 150 to 156 | Relay short or open circuit Log and reset. A repeat points at the main board. |
| 120 to 124 | Cooking zone overheat Check whether thermocouples are cross connected on the user control. |
| 130 to 136 | Triac fault Check element connections and resistance, 18 to 20 ohms, before the board is condemned. |
| 139 | User panel overheat Check door seals, a door left open, missing insulation, or towels over the panel door. |
| 140 | Configuration key fault No key fitted, or the wrong key for the phase of the electrical supply. |
| 159 | Handset RF fault The receiver is not communicating with the board. |
| FE | Touch panel microcontroller unresponsive A reboot may clear the fault. |
| CE | No response from main controller Check the connection and condition of the COMS cable. |
Codes 004 and 005 are listed as not used. Note how many of these faults point away from the expensive part: 120 to 124 can involve wiring on a previous visit, 139 can involve a door seal, 140 can be a missing key, and 130 to 136 calls for a resistance check before anyone orders a board.
