Ilford ICP-42 Relay Replacement Part?

[Koakashii]

Hey everyone,

I’m troubleshooting my Ilford ICP42 Processor that is currently powering on and the circulating pumps working fine but it’s running for around 20-30 mins then shutting off possibly due to the exhaust fan not powering up which I had replaced with a new one and the water heater possibly not working correctly all of which I’m thinking is pointing to the relay being damaged or old so I’m looking for a replacement for it which I cannot find anywhere not even a equivalent one. So any help is greatly appreciated and welcome!

,Thank you

Look for dealers of obsolete electronic components. Surplus stuff. Is this rebuildable?

Yes the processor as it stands is about 85% operationally solid I just need to replace this relay block I’ve multimeter tested all other cables and possible factors!

Relays are generally commodity-type devices, and it ought to be fairly straightforward to find a replacement, though the case style and connectors may vary.

From what I can see, yours appears to be a Single Pole, Double-Throw switch with contacts rated at 220V/15A or 380V/10A, alternating current. It is activated by a coil rated for 110V, 60 Hz, presumably also alternating current. Do you know what sorts of voltages and currents are actually being switched, and whether they are AC or DC?

You might consult a museum these machines go back 50 years or more . Here's a listing at the V&A.

Before randomly replacing the relay, test it first.

If you want to replace it, any relay with the same or more generous specifications can be substituted as long as you can make it physically fit in the box. This should not be particularly difficult to find. At first glance it looks like the coil switches with 110VAC and the contacts will probably need to be rated for only a couple of amps at probably also only 115VAC if you're going to run in the US and it indeed only switches the fan.

Relays can generally be found under "Electromechanical". You can narrow down the selection based on the ratings printed on the original part.

Single pole, double-throw type switch (SPDT)
One circuit Normally Open (NO), the other, Normally Closed (NC)
Non-latching would be most common type

Although the current ratings for the original part seem awfully generous, there's likely a reason for it: perhaps there's a hefty surge when breaking contact with an inductive load, or circuit is actually DC.
