Boiler and Air Conditioner Board Repair in Baku

Boiler control board repair in Baku — circuit board repair for combi boiler brains, inverter air conditioners, chillers, VRV/VRF, washing machines and refrigerators: error codes, no-start faults and burnt IGBT modules.

Order

Send the make and model and describe the fault briefly. A video helps most — film the fault. Clear photos of the board help too.

Electronics repair for boiler (combi) boards, inverter air conditioners, chillers, VRV/VRF systems, washing machines, refrigerators and dishwashers. Component-level circuit board repair: power section, relays, IGBT modules and microcontroller recovery.

⚠️

Not every device can be repaired

Sometimes restoration is not possible: the chip is discontinued and no spare can be sourced, no donor board is available, the board is severely damaged by fire or liquid, or earlier repair attempts have left it beyond recovery. In such cases we explain the situation plainly and, where possible, suggest an alternative.

When a combi boiler board — often called the boiler's brain — fails, the appliance either will not start at all or locks out with an error code on the display. We do not swap the control board wholesale: we locate the fault at component level and restore only the failed part. That gives the board a new life and costs several times less than a full replacement.

Alongside boilers we take in inverter air conditioners, chillers, VRV/VRF systems, washing machines, dishwashers and refrigerator control boards — in all of them the work is circuit board repair rather than whole-module replacement. The cases we see most: a boiler showing an error code (F04, E01 and the like), a burnt IGBT module in an air conditioner outdoor unit, a washing machine stopping mid-programme, a refrigerator's inverter compressor drive gone dead.

In this group the power section is the most common source of trouble: mains voltage surges, dried-out capacitors and welded relay contacts. Boilers add the ignition-ionisation circuit as a weak point, air conditioners the IGBT and PFC module. An error code only tells you which circuit is not responding — measurement finds the cause.

Common faults we repair

  • The boiler board will not start, shows an error code (F04, E01 etc.)
  • The boiler will not ignite, there is no spark
  • It heats water but the heating circuit does not work
  • The display is dark, the buttons do not respond
  • A burnt IGBT / PFC module in the air conditioner outdoor unit
  • The air conditioner starts, then stops after a few minutes
  • A communication error on the chiller / VRV / VRF control board
  • The washing machine stops mid-programme
  • The washing machine motor will not turn, no tacho signal
  • The dishwasher control board reports a water fault
  • The refrigerator's inverter compressor drive is dead
  • The relay clicks but the load does not switch on

Typical causes of failure

  • A burnt power section after a mains voltage surge
  • Control voltage dropping as capacitors dry out
  • Failed elements in the ignition and ionisation circuit
  • Corrosion on the board from a water leak or steam
  • A punctured IGBT or PFC module in an inverter air conditioner
  • Welded relay contacts
  • Static discharge on an unearthed line
  • Overheating after long service in a dusty environment

How the repair works

  1. 01

    Enquiry and first contact

    Tell us about the fault on WhatsApp or Telegram. We review what you send and let you know whether the device fits the work we take on.

  2. 02

    Acceptance and diagnostics

    If we can take the device on, we confirm it in advance — do not ship it before you have our confirmation. Once it reaches the lab, diagnostics are completed within 48 hours (two working days).

  3. 03

    Estimate and approval

    You receive a report covering the cause of the fault, the estimated cost, spare-part availability and the timeline. Work begins only after you approve it.

  4. 04

    Testing and handover

    After the repair the device runs a minimum 24-hour load test. Once it proves stable in normal operation, we report the result and hand it over.

Diagnostics and pricing

Diagnostics is paid work — 10–50 AZN depending on the complexity of the board. If you have us carry out the repair, that amount is deducted from the final price. An exact repair price is given only after diagnostics and is agreed with you before any work starts.

Frequently asked questions

Request a repair

Message us on WhatsApp or Telegram with the BRAND and MODEL of the device and describe the fault in as much detail as you can. A VIDEO helps most: record the fault and explain in your own words what happens. Also send clear photos of the device and, if accessible, of the circuit board from several angles. The more detail you provide, the faster and more accurate our answer.
