SupplyHouse is great. The part operates fine but it was advertised as a 30 second timer. After installation (no delay on thermostat) the timer operated at something between 3 and 5 minutes. The part matches the description, so I'm not sure what to say...other than the customer who needed this is happy to be back in operation even with a 3-5 minute delay in the event of a short cycle or power outage.
