Carrier Extra reefer unit F4 fuse

[toocoldtoohot]

Hello, The F4 fuse blew. The blown one had 20 amp on it, replaced now with same. Need to make sure it's the right amp and need to know for what the fuse is. I was trying to get the info on the carrier website, but to no avail. Just can't find the "Extra" unit anywhere else as well.
Thanks for your help in advance.

That's what I want to know. What is the F4 fuse?Hot gas fuse?Solenoid fuse?Fuel heater fuse?I don't have a manual for the Carrier "Extra" model. Does anyone have the information?

I think F4 is the speed solinoid fuse and should be 15A i think

what micro does it have the advanced or the standard ?

F4 on the advanced is the clutch(7.5a)
F4 on the standard is the speed relay(15a)

I naturally assumed a std micro as an advanced would have given more indication of the fault?
