[* black] No Internal light working and lower oven function or display. Note that this oven has two similar control pcb's. You can compare one board to the other.
[* black] The lamp has been replaced but still not working. The next thing to do is check out the lamp socketwire end connections, the terminals as these went high resistance on my unit, replacing the push on connectors was easy. The connectors are the type used on cars and I had some handy. Re-testing still not onno light.

[* black] Tracing the lead wires back to the control pcb I noticed the small relay (Omron pcb relay GQ5 1A) looked bad and this only applied a neutral return.
[* black] Pulling the relay shouldshowed more blackenblackened marks. So the relay was replaced. Radio(Radio Spares part. xxx-xxxxpart number 434-1563, cost £2.27p) Success now the light was on again.
[* black] Moving on to the lower oven with no display or function buttons working. Checking the output from the small 12v 5VA transformer was zero. 240V AC input was there. A slight bulge on the top of the transformer confirmed a problem, it was also coming out. Resistance on the primary showed o/c windings.
[* black] A new replacement from Farnnell was fitted. Part number xxx-xxxx1689081, (Manufacturer part number 44231)
[* black] Testing and the controls were restored to normal.
[* black] Just a note to say the new transformer was made by Myrra (not Tamura as in the photo) and that a Myrra unit was on the second
