Troubleshooting & panel upgrades
Production down? Panel obsolete? We diagnose, repair and modernize thermal control systems — for new and legacy equipment alike.
From cold-start diagnostics to full panel rebuilds
Thirty-plus years of thermal systems experience means we've seen the failure mode. If it heats, senses or controls, we can troubleshoot or upgrade it.
Production-Down Troubleshooting
Cold zone, erratic temperature, nuisance trip or controller fault — we walk you through diagnostics by phone or arrive on-site within the hour (Upstate).
Panel Upgrades & Retrofits
Replace obsolete relays, dead controllers, non-UL wiring or missing documentation with a modern panel — often in the same enclosure footprint.
Heater & Sensor Diagnosis
Megger tests, resistance checks and thermocouple polarity verification to find the failed component in seconds, not hours of guessing.
Control System Tuning
PID auto-tune and manual optimization for overshoot, oscillation or slow response — so your zones track setpoint without chasing.
We don't walk away from old equipment
Machines from the '80s and '90s are still running in plants across the Upstate. Their panels may be undocumented, their controllers obsolete, their wiring undocumented — but they still heat.
- Trace and rewire undocumented panels
- Cross-reference discontinued controllers
- Match obsolete heater form factors to modern equivalents
- Source rare thermocouple and RTD connectors
- Document as-built wiring for future maintenance
Troubleshooting & upgrade FAQ
Call us first — many issues resolve over the phone in under 15 minutes. For Upstate SC facilities, we can have a technician on-site within the hour. We also ship same-day on stocked replacement parts.
Yes. We trace the wiring, identify components, create as-built documentation, then design the upgrade or retrofit. You get a fully documented panel and the knowledge to maintain it going forward.
Absolutely. We service and upgrade thermal systems regardless of who designed them. If it involves heating elements, temperature sensors, PID control or power switching — it's our domain.
Both are fine. Many customers upgrade one problematic loop at a time — swapping a failing controller or adding over-temp protection to a specific zone — without a full panel rebuild. We'll scope what makes sense for your budget and downtime window.
Problems we see every week
Thermal systems fail in predictable ways. Knowing the symptom saves hours of downtime.
Cold Zone
Heater open, relay stuck, SSR shorted, or controller in manual. We identify the break in the loop in minutes.
Temperature Drift
Aging thermocouple, contaminated RTD junction, or cold-junction reference drift. We swap and recalibrate.
Nuisance Trip
Oversized fuse, inrush exceeding breaker curve, or ground fault in heater sheath. We resize or isolate.
Controller Fault
EEPROM corruption, failed output relay, or wrong sensor type selected. We repair or cross to a current model.
Production down? We'll get you running.
