In this post, we will dive into specific fault codes for the Melink Intelli-Hood 2 (IH2) system…
Over the years, Melink Corp has designed and implemented three Intelli-Hood® systems: IH1, IH2 and IH3. Each system has its own specific configurations. While all work on the same basic principles, they DO NOT have the same parts or interfaces. Not sure what system is in your kitchen? Click here.
Intelli-Hood 2 Faults
The IH2 reference guide does not list every possible fault. Instead, it includes a code guide, which can be confusing to interpret, especially if the system has multiple hoods.
Please note that everyday kitchen staff should not be expected to understand these faults; the intention is for a contractor or electrician to be handling fault issues.
Intelli-Hood 2 Fault Code Guide
This code guide should be used for diagnosing IH2 fault codes.
F = Fault
1, 2, 3 or 4 = Identifies the hood number, i.e. H-2 means Hood 2
h-1-e = 100%
H or h = Temperature fault
H = Sensor fault code relating to high temperature or open circuit/high resistance
h= Sensor fault code relating to low temperature or low resistance
U = VFD fault
Note: U faults will normally be followed by another code. If you don’t have a second code, the system is not recognizing the VFD, i.e. no power is going to it.
O = Optic fault
o on bottom of display = Low optic signal
o on top of display = High optic signal or saturation
F-PH = Phone line
Note: Either the phone line connected to it is no longer there or the modem itself is bad.
