HOB OVENS Product Lines We Repair
Our engineers are trained on the full HOB OVENS product range. Below are the major product families we service.
HOB Convection Ovens Series
Industrial convection ovens with forced air circulation for uniform baking and drying. Common issues include thermostat failures, fan motor breakdowns, temperature sensor drift, and control relay failures causing uneven heating or temperature overshoots.
HOB Tunnel Ovens
Continuous-feed tunnel ovens for high-volume bakery and confectionery production. Typical faults include zone thermostat malfunctions, chain drive encoder failures, burner ignition control circuit faults, and temperature zone imbalance issues.
HOB Rotary Ovens
Rotating tray ovens for batch baking with precision temperature zones. Common repair needs involve rotary motor speed controllers, tray position sensors, zone damper actuators, and PLC interface boards.
HOB Pharmaceutical Drying Ovens
Specialized drying chambers with programmable temperature ramps and humidity control for pharma and nutraceutical applications. Frequent issues include humidity sensor calibration loss, vacuum pump relay failures, and data logging system crashes.
HOB Temperature Control Panels
Standalone digital control panels and legacy analog thermostat systems for oven operation. These panels manage heating elements, fan speeds, and safety interlocks. Repair issues include PID algorithm faults, analog input card failures, and relay card burnouts.
HOB Element Drivers & Power Modules
Solid-state heating element drivers and SCR-based power control modules for electric heating. Common faults involve SCR thyristor short circuits, gate drive circuit failures, and over-temperature shutdown triggers.

Common HOB OVENS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HOB OVENS equipment arriving at our workshop.
- ✓Temperature zone uneven heating during baking — HOB Ovens multi-zone control panels often develop thermostat sensor drift or broken thermocouples in specific zones. Heating element drivers may also have failed SCR modules causing reduced power to certain zones.
- ✓Tunnel oven chain stops or runs erratically — HOB Tunnel Oven motor speed controllers develop capacitor leakage, and chain position encoders fail due to vibration and thermal stress. Control relay contacts can also stick or chatter.
- ✓PLC data logging stops or historical data corruption — HOB Ovens PLC systems — typically Siemens or ABB embedded units — experience SD card failures, memory module corruptions, or real-time clock battery depletion. Ethernet interface cards may also fail.
- ✓Burner ignition fails or pilot light extinguishes — HOB gas-fired ovens lose spark ignition due to faulty ignition transformer, failed spark electrode gap, or clogged gas valve solenoid coil. Control relay circuits may also be burned out.
- ✓Humidity sensor reads zero or drifts continuously — HOB Pharma Drying Ovens use capacitive humidity sensors that become saturated with moisture, corroded by salt deposits, or lose calibration. Sensor signal conditioning circuits may also drift.
- ✓SCR power modules over-temperature shutdown triggers repeatedly — HOB heating element drivers experience SCR thermal runaway due to failed cooling fans, blocked heat sinks, or shorted gate drive circuits causing continuous SCR firing.

Frequently Asked Questions — HOB OVENS Repairs
Do you repair HOB Ovens equipment anywhere in India?+
Yes. Synchronics repairs the full HOB Ovens product range — tunnel ovens, convection ovens, rotary ovens, control panels, element drivers, and sensors. We offer PAN India pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Repairs happen at our main facility in Vadodara, Gujarat, with typical turnaround of 5-7 working days.
What is your turnaround time for HOB Ovens temperature control panel repairs?+
Standard HOB Ovens panel repairs — thermostat calibration, relay card replacement, sensor troubleshooting — take 5-7 days. Complex multi-zone systems requiring PLC reprogramming or firmware updates may take 10-14 days. Emergency express service is available for critical production lines; contact our dispatch team for same-day evaluation.
Can you repair legacy HOB analog thermostat panels?+
Absolutely. Synchronics has extensive experience with HOB's analog thermostat systems and older non-digital controllers. We repair analog control cards, test mechanical switches, replace failed potentiometers, and re-balance control circuits. We also provide migration paths to modern digital controllers if analog components become obsolete.
Do you offer preventive maintenance contracts for HOB Ovens?+
Yes. Synchronics offers annual and quarterly preventive maintenance contracts for HOB Ovens facilities. Services include thermocouple inspection, sensor calibration, SCR testing, control relay checks, cooling fan cleaning, and thermal imaging. Contracts reduce downtime by 40% and extend equipment life by 3-5 years. Contact our service planning team for customized packages.
What warranty do you provide on HOB Ovens repairs?+
All Synchronics HOB Ovens repairs carry a 12-month parts and labor warranty. Repaired components are tested under load conditions mimicking actual oven operation. We provide spare parts kits and emergency contact numbers for warranty support. Extended 24-month warranties are available for critical production equipment.
How do I send my HOB OVENS 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 HOB OVENS 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 HOB OVENS 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 HOB OVENS 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.
