1. Temperature Inconsistencies
Problem: Uneven heating or failure to reach target temperatures
Causes:
Worn heating elements
Faulty temperature sensors
Improper calibration
Insufficient preheating time
Solutions:
✔ Replace aging heating elements (typically every 2-3 years with heavy use)
✔ Calibrate thermocouples annually using NIST-traceable standards
✔ Allow 20-30 minutes preheat for temperature stabilization
✔ Rotate samples periodically for even exposure
2. Excessive Energy Consumption
Problem: Sudden spikes in power usage
Causes:
Deteriorating insulation
Door seal degradation
Oversized furnace for application
Frequent door openings
Solutions:
▲ Replace ceramic fiber insulation when efficiency drops >15%
▲ Install new high-temperature door gaskets annually
▲ Right-size your furnace capacity to sample volume
▲ Minimize door openings during runs
