Moen 1225b question...

Yesterday I replaced a kitchen faucet cartridge supplied by Moen. Tested it out, hot on the left, cold on the right. Got a text this morning from my customer saying that hot is only warm.

I’ve seen positemp cartridges act as a mixing valve, but not a push pull.

I’m heading north today to winterize a cabin so I won’t be able to get back there until next week. Any other ideas? Just tell him to order another?
