Rewiring a Light Switch that Feeds Another Light Switch

I replaced the switch with a new switch, now the pantry light works, but the range light fan doesn’t. How to Change the Wiring of a Light Switch.

Light Switch Wiring
Electrical Question: I replaced the switch with a new switch, now the pantry light works, but the range light fan doesn’t.

I have a pantry light wired to a switch in which the toggle broke off. Upon removing it I discovered it’s a 3-way switch. However, it’s not paired with another 3-way switch.

Turns out since it’s such a small house, the original owners or builder, wired the above-the-stove range light/fan to the switch for a power source. The switch only works the light. The fan/light above the stove has it’s own switch. So I replaced the switch with a new 3-way switch last night.

However, the pantry light works like a charm, but now the range light/fan doesn’t. I have the black wire from the pantry light connected to the “hot” black terminal and the other two connected to the traveler terminals.

Where did I go wrong? Thank you in advance!
