In bakeries, biscuit workshops, and restaurant kitchens,BlodgettConvection ovens are known for their stability and durability.
But even with good equipment, motor faults that “seem to be complex but are actually deeply hidden” may occur after many years of operation..
Blue Sky door-to-door maintenance teamIn a recent real case:
❌ Oven powered on
❌ The fan sometimes starts and sometimes does not start
❌ The relay cannot be fully closed during heating
👉The root cause is not the heating system, but poor contact in the centrifugal switch inside the fan motor.
Final plan:
✔️Replace fan motor
✔️ The system returns to normal
✔️ Solve the problem once and for all
1. Common fault types of Blodgett convection oven (high frequency)
🔹 1️⃣ The oven does not heat / heating is unstable
Often misdiagnosed as a heating pipe or control board problem
Actual possible reasons:
-
The fan is not operating properly
-
Safety interlock logic is not satisfied
-
Relay cannot fully close
👉 Convection Oven:Without a stable fan, stable heating is not allowed
🔹 2️⃣ The fan starts abnormally (the core of this case)
Performance:
-
Occasionally normal when cold machine
-
The problem worsens as the temperature rises
-
Operation interruption and repeated restarts
Real reason:
-
Poor contact of the centrifugal switch inside the fan motor
-
Resistance change after heating
-
The relay cannot be fully closed and the system determines that it is abnormal.
Processing method:
-
Detect the operating status of the fan motor
-
Confirm centrifugal switch problem
-
Directly replace the motor assembly (the most reliable solution)
🔹 3️⃣ Relay and contactor are abnormal
Notice:
-
Many times the relay itself is "implicated"
-
The root cause is that the fan or interlock conditions are not met
👉If you only replace the relay, the problem will easily recur
2. Why is this kind of failure a "technical issue"?
⚠️ This is typicalMotor + control logic + thermal fault:
-
Cold measurements may be fine
-
The problem is only revealed when the temperature rises
-
Non-experience maintenance can easily lead to misjudgment
🛠This type of repair:
❌ Normal maintenance will only replace the relay
❌ Or check the control panel repeatedly
✔️ But the real problem lies in the internal structure of the motor
👉Judging whether to decisively change the motor is a matter of experience.
