AEG-ELOTHERM Equipment We Repair — By Category
AEG-ELOTHERM Product Lines We Repair
Our engineers are trained on the full AEG-ELOTHERM product range. Below are the major product families we service.
Induction Heating Generators
High-frequency induction heating systems for metal hardening, forging, and tube welding. Common faults include oscillator tube failure, matching network instability, and water-cooled coil blockages causing thermal runaway.
Dielectric Heating Units
Industrial dielectric heaters for plastic curing, resin processing, and composite manufacturing. Failures typically involve high-voltage electrode degradation, dielectric breakdown, and frequency drift under load.
Temperature Control & Monitoring Systems
PLC-based thermal management and process control systems with analog/digital I/O. Repair needs include firmware corruption, sensor interface failure, relay card burnout, and display module malfunction.
Power Electronics & Capacitor Banks
High-voltage DC link capacitors, IGBTs, and power module assemblies for heating generators. These experience electrolytic leakage, capacitor swelling, IGBT gate drive failure, and snubber circuit breakdown.
Frequency Converters & Matching Networks
Variable frequency drives and impedance matching transformers for induction heating circuits. Common issues include resonance loss, matching network detuning, ferrite core saturation, and primary winding insulation failure.
Oscillator Modules & Feedback Systems
RF oscillator cards, phase-locked loop feedback circuits, and sensor conditioning boards. Failures involve tube degradation, crystal oscillator drift, feedback loop instability, and aging of cathode heater supplies.

Common AEG-ELOTHERM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AEG-ELOTHERM equipment arriving at our workshop.
- ✓Oscillator tube secondary emission failure — AEG-ELOTHERM induction generators rely on vacuum tubes for RF generation. After 15,000-20,000 operating hours, tube cathode emission degrades, output frequency collapses, and the generator enters frequency-hunt mode or shuts down.
- ✓Matching network detuning and power loss — AEG-ELOTHERM matching networks use variable capacitors and taps to tune load impedance at operating frequency. Mechanical wear, capacitor plate contamination, and thermal cycling cause network Q-factor collapse and standing wave ratio (SWR) degradation.
- ✓DC link capacitor electrolytic leakage and swelling — High-voltage electrolytic capacitors in AEG-ELOTHERM power supplies experience accelerated aging under thermal stress from heating coil proximity. Leakage current increases, ESR rises, and voltage regulation fails, triggering overvoltage shutdown.
- ✓PLC temperature sensor interface malfunction — AEG-ELOTHERM thermal controllers use Pt100 or thermocouple inputs interfaced via signal conditioning boards. Connector corrosion, amplifier offset drift, and ADC linearity loss cause false temperature readings, triggering nuisance alarms or out-of-spec heating.
- ✓IGBT gate drive circuit failure in power modules — AEG-ELOTHERM IGBT stacks rely on isolated gate drive transformers and opto-isolator circuits. Thermal stress degrades transformer coupling, opto-LED emission fails, and gate signal timing becomes erratic, causing IGBT short-circuit or shoot-through.
- ✓Resonant circuit damping and bandwidth collapse — AEG-ELOTHERM induction heating circuits operate near resonance for maximum efficiency. Aging of tank circuit components (L, C, R) and feedback loop drift cause resonance peak flattening, frequency stability loss, and poor load coupling.

Frequently Asked Questions — AEG-ELOTHERM Repairs
Do you repair AEG-ELOTHERM equipment anywhere in India?+
Yes. Synchronics repairs the full AEG-ELOTHERM thermal heating and process control product range — induction generators, dielectric heaters, temperature controllers, power modules, and oscillator systems. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs are processed at our ISO-certified facility in Vadodara, Gujarat.
Why does my AEG-ELOTHERM induction generator lose frequency stability under load?+
Frequency drift in AEG-ELOTHERM generators typically stems from phase-locked loop (PLL) feedback instability, aging oscillator tubes, or matching network detuning. As load impedance changes, the PLL correction bandwidth may be too narrow, causing hunting behavior. Synchronics diagnoses the root cause via frequency sweep analysis, replaces worn tubes if needed, and retuning the feedback loop to maintain ±0.5% frequency accuracy across your load range.
What is the typical lifespan of AEG-ELOTHERM oscillator tubes?+
AEG-ELOTHERM vacuum tube oscillators have a design life of 15,000-20,000 operating hours before cathode emission degrades significantly. In 24/7 foundry or automotive heat-treat environments, this translates to 18-24 months. We recommend preventive tube replacement when frequency margin drops below 10% to avoid unscheduled shutdown. Synchronics stocks genuine and equivalent replacement tubes and provides rapid turnaround.
Can Synchronics repair AEG-ELOTHERM matching network tuning failures?+
Yes, absolutely. Matching network tuning is a core AEG-ELOTHERM repair competency for us. We perform impedance analysis, identify capacitor plate wear or tap contact degradation, clean and realign components, and recalibrate the control loop to restore tuning accuracy. Return loss is verified at your operating frequency to ensure maximum power transfer to the load coil.
What warranty do you offer on AEG-ELOTHERM repairs?+
Synchronics offers a standard 12-month warranty on all AEG-ELOTHERM repairs covering parts and labor. Extended 24-month warranties are available for critical equipment. If a repaired unit fails within warranty due to our workmanship, repair cost and shipping are covered. We also offer on-site installation support and commissioning at Indian plants.
How do I send my AEG-ELOTHERM unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AEG-ELOTHERM drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AEG-ELOTHERM repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AEG-ELOTHERM unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
