Free PCB test card with gas training courses

New Harness Test PCB

A new credit-card sized Harness Test PCB has been developed by Worcester for installers.

The harness allows the engineer to check Greenstar gas boiler PCBs without damaging the edge connector (by trying to force the probes of an electrical tester into the connections).

The Harness Test PCB is being given away - for free - on all Greenstar gas boiler training courses.

The Harness Test PCB features and benefits:

• Handy credit card size
• Compatible with all Worcester Greenstar boilers (including older models)
• Annotated with sensor names for simple measurements
• Provides easy access to harness and components
• Faster fault diagnosis (reduced time on site)
• First-time fix rate increased
• Component changes minimised - lower cost to homeowner
• Allows installer to fix problem themselves - fewer engineer call-outs

How the harness test came about

The harness test was developed by Colin Davies, training supervisor at Worcester, and Richard Forrester, Worcester’s electrical controls engineer.

Colin explains:

“Installers were telling me that the current method of testing the PCB on our boilers is fiddly. So, Richard and I put our heads together and created the credit card sized harness test PCB.

“It’s small enough to fit into the PCB without having to struggle to fit it in but large enough not to be difficult to handle.”

Great response from installers

With over 1,000 units already in use, Worcester has received a great response from installers.

One heating engineer, Mr T Griffiths, commented:

“This is the best diagnostic tool I’ve used, now I can exactly pinpoint the problem on the boiler and confidently leave my customer with a working heating system.”

Gas courses

All installers attending a gas boiler training course from Worcester will receive the new Harness Test PCB for free!
