Landlord Pays for Stove Broke by Tenant???

[Anthony McEvoy]

I had a glass top electric stove in one of my rental properties.  The tenant did something where the glass top cracked - they most likely dropped something on it.  The stove was old and the property manager claimed they could not find a replacement glass.  Therefore, a new stove was purchased and installed.  I noticed on my last statement that the property manager did not back charge the tenant nor is it their intention.  After questioning my property manager about the situation, they responded in an email stating:

The stove was around 15 years old and when it broke, we couldn’t get the part to fix it and we cannot charge resident for something that old. But we did charge resident the charge to install it.

Does the age of the stove matter?

If the tenant never broke the glass top, then it would have still been working as intended.  I am impartial if these tenants stay due to multiple facets of this property and the situation as a whole.
