Manaut PCB GLM 4 Ref. 87167210190

If your boiler does not start, gets blocked, or behaves erratically, a technical diagnosis must confirm if you need the PCB Biasi GLM 4, reference 87167210190. This component controls the ignition, burner modulation, pump, and safety features of the boiler. In case of a fault, you will notice that the boiler does not operate correctly. It is compatible with models such as GLM 4 and GLM 4.16, among others. A technician must confirm through diagnosis if it is necessary to replace it when it shows operational faults.

Guide

How to check if the ref. 87167210190 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 87167210190. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms that require diagnosis on the PCB 87167210190

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 boiler does not ignite at all: neither the fan, nor the pump, nor the ignition spark.

    Cause: The PCB does not send the start command to the components because it is faulty.

    Check if there is power reaching the PCB before replacing it; a previous power failure can cause the same symptom.

  • 02

    The fan or the pump continues to operate even after you have turned off the boiler.

    Cause: A relay on the PCB has become stuck and continues to send current to the component.

    Listen for the relay clicking when turning off; if it continues to operate without that click, the relay has not opened the contact.

  • 03

    Sometimes it starts up well and other times it doesn't respond, without a clear pattern.

    Cause: An intermittent fault in the relay circuit causes the start command to arrive sometimes and not others.

    Gently tap the boiler casing when it fails; if the fault appears and disappears with the tap, it may be a poor connection on the PCB.

  • 04

    The boiler does not respond when adjusting the temperature from the control.

    Cause: The control circuit of the PCB does not process the signal from the remote control.

    Turn off the main power and wait half a minute before turning it back on; sometimes the circuit gets stuck without being 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.
