Roach infestation destroyed oven

[Chris Berry]

Just seeing what is the correct thing to do.  The plumber let me know while fixing a leaky faucet the house is filled with roaches.  The same day she let me know a 3 yr old oven has an error code.  I sent whirlpool tech to look at the circuit board and was informed the oven was infested with roaches and destroyed the circuit board and probably other components.  I sent a gel I've used in the past and informed her I need to take care of the infestation prior to buying a new oven so they don't destroy the brand new one.  Is it in my right to wait a few days to see if the gel works like I anticipate, or I need to buy a new one immediately?  She keeps saying she can't wait for the oven.
