new convection oven wiring

We have a double oven with stove all in one that we are replacing with a electric range/stovetop and separate convection microwave oven above. The microwave requires a 110 receptacle directly above it which happens to be where a short set of cabinets is. I have 6 double outlets in the kitchen already. Was going to move one but all the wiring is horizontally through metal studs behind the cabinets. My breaker box looks full. I have outside box with a 150amp breaker and 20amp breaker labeled pool equip. In the garage I have a 30 slot panel all slots taken. Breaker on the odd numbers slots are 40, 40, 30, 20, 20, 20, 20, 20, 20, 20, 20, 15. The even slots are 50, 30, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15. The 50/40s/30s are taking 2 slots. What are my options?

 

Welcome to the forums.

The separate convection microwave oven requires its own single 20A breaker.
The electric range may require a two pole 50A breaker.

It sounds like you are tight on room there. You may be forced into installing a sub panel.
The breaker sizes you wrote down don't really help us much. You need to write down what is on each breaker..... more importantly...... the double ones.

 

A sub panel is the most reasonable option.

 

double slots are:
1-3 40 amp is range/exhaust
5-7 40 amp is furnace
7-9 30 amp is water heater
2-4 50amp is A/C
6-8 30 amp is dryer
