PCB GLM5 (Bosch/Junkers, ELM Leblanc) Ref. 8716736065
GLM5 PCB (Bosch/Junkers, ELM Leblanc) Ref. 8716736065 is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or behave erratically. This board is compatible with models such as GLM5 13, GLM5 20, and ELM Leblanc GLM 5, among others. A technician must confirm through diagnosis whether it needs to be replaced when these operational issues occur.

How to check if ref. 8716736065 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 8716736065. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis on the PCB 8716736065
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The fuse on the PCB blows as soon as the boiler is started.
Cause: A short circuit in any component connected to the PCB (pump, valve, electrode) can damage the output stage and blow the fuse.
Disconnect the pump and the gas valve and check if the fuse blows again to rule out an external short circuit.
- 02
The boiler is dead, with no indicators or response when pressing anything.
Cause: With two 1A fuses on the PCB, it is enough for one to be blown to cut off power to the entire electronics.
Check the status of both fuses with a multimeter before declaring the PCB faulty.
- 03
The boiler starts up well but occasionally shuts down by itself without a fault code.
Cause: In a control board of this age, fatigued solder joints or degraded components cause intermittent faults that are difficult to replicate.
Note at what moment the blackout occurs (start-up, steady state, demand change) before replacing the PCB.
- 04
The room thermostat or the programmer clock cannot get the boiler to start.
Cause: The input stage of the PCB that reads the external demand may be damaged.
Do not bridge contacts or power components directly to test them. Request a technician to check the cause according to the model manual and its revision, without bypassing the protections. The symptom or fault code does not confirm on its own that this part is faulty.
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
