How to troubleshoot no blower operation in Cambridge Engineering S1600 Heater?
- J
  Jennifer MillerAug 5, 2025
  If the Cambridge Engineering Heater blower isn't running, first ensure the unit isn't in reset by turning it OFF and then ON again. Check that the heater disconnect is ON. Verify the mode selector switch on the RCS is in the correct mode and adjust the operating thermostat if needed. Make sure the blower service switch is in the REMOTE position. Examine the control and Class 2 transformers, checking the disconnect, supply fusing, and supply voltage. Also, inspect the multi-functional PC board, checking the voltage in the RCS. Other potential causes include the damper motor (adjust damper stroke), motor protection/starter/motor (check primary power source or replace starter), blower (replace bearings), or belts (tighten belts).

What to do if Cambridge Engineering S1600 Heater modulating valve does not modulate and runs on continuous high fire?
- J
  Jordan Davis DVMAug 9, 2025
  If the Cambridge Engineering Heater's modulating valve is stuck on continuous high fire, try reinstalling the wire on the amplifier (A1014, A1044, or AD1014). You might also need to clean the Discharge Air Temperature Sampling Tube for the discharge temperature sensor (TS114J or TS144). For Series 44 models, replace the space temperature selector if resistance exceeds specified values (7,000 ? for T244; 5,500 ? for TS244; or 2,250 ? for TD244). For Series 14, recalibrate or replace the space thermostat. If using a remote heat adjust (TD114 or CEI 4175-0-960), replace it if resistance between terminals 1 and 3 is less than 6,000 ?.

What to do if Cambridge Engineering S1600 blower runs, but there is no heat and flame safety relay locks out?
- I
  ijohnsonAug 13, 2025
  If the blower runs but the Cambridge Engineering Heater doesn't heat and the flame safety relay locks out, start by checking the igniter current. Also, check the gas supply for low or no gas pressure using the high or low gas pressure switches. Inspect the gas valve, verifying the FSR output to the R1 relay during ignition. Finally, adjust the minimum fire on the modulating valve.

Why Cambridge Engineering Heater blower runs, unit heats, but will not cycle off?
- T
  Teresa CampbellAug 18, 2025
  If the Cambridge Engineering Heater blower runs, the unit heats, but it won't cycle off, first check the thermistor wiring and consider replacing the thermistor for the operating thermostat. Ensure the burner service switch is in the REMOTE position. Inspect the auxiliary circuit wiring and contacts. Consider reviewing the control system's operational characteristics to ensure proper understanding.
